My AK Blew Up! Zastava Zpap M92
ฝัง
- เผยแพร่เมื่อ 11 ก.ย. 2024
- As stated.. My AK blew up. I try to summarize on what happened. the tifle is a Zastava M92 or Zpap M92. It ran most of its life suppressed with a KNS piston running as soft as it could to run reliable. Shooting a mix of corrosive surplus and brass S&B ammo. I want to tag some of the names I appreciate a lot in the gun world, especially the AK community.
Thank you all.

Never apologize for potential bad english, your english is better than than some native english speakers....
even when its their only language.
its definatly better than any of the languages ive tried learning, and currently am learning.
That sucks man. Glad you were not hurt at least!
Thanks. I appreciate the thought
Contact zastava and ask them to look at it. Worst case they do nothing, but possibly they send you a replacement at a big discount. I hear they are great at support.
Zastava CS in Serbia is not the same as CS in the US 🙂. But i'll give it a shot
I don't think Zastava has that good cusomer support,but would be great!
@@mrsinflames we'll find out 🙂
This isn't zastava this isn't a zpap he's got to contact century arms this is definitely not a zpap u can tell by the non bulged trunnion
@timothycain4512 never heard of a bulged trunion. This is a genuine Zastava arms M92. Not a US import. We are discussing metalurgy here not nomenclatue. But since.. Zpap stands for Zastava pol automatska puska. The opap and npap are just import nomenclatures designating import batches. You're welcome
As an AK builder , my opinion is of two things. The bolt didn't lock up all the way , excessive headspace or it didn't seat all the way. Second opinion is the ammo was loaded up way too hot. Thats an extremely rare occurrence ! Im betting on headspace. But the way the bolt lug rolled makes me think of extremely high chamber pressure. I have never seen that before other than on cast trunnions. Anyways hlad youre okay and have all your finggies !
Yea the way it destroyed the back of the trunnion doesn't look like it was in battery
ZSR has done this to 7 AK and they have rebranded their ammo. He got lucky it didn't shrapnel and it was lugs that shat.
Great observation. My first impression was an over loaded round. There have been examples of ammo from Turkey - NOT 7.62X39 but as I recall 30-06 or similar in a batch that was excessively loaded with propellant, leading to some problems with as I recall bolt guns. That is from my recollection and I have not googled the articles etc., but that was within the past three years, here in the US. Your observations on the Bolt wear were spot on also. Might it possibly be a combination of over loaded ammo AND excessive head space at that critical split second in time?
I would gamble it has a KNS and set very low causing light battery and wear. I have seen this before with Izzy and Arsenal when the gassing is super low and the bolt has really hot loadings.
Damn, you're explaining my mac 90 that I haven't shot due to the go no go being just so close to being out of spec. What would you do in that instance on a never fired outside of the factory gun? Re drill it?
Yikes.. luckily you didnt get hurt. If you send it back to Zastava make an update video
Your english is fine brother.
1) gas system pressure has nothing to do with this. If a rifle is over gassed it will just extract violently, tear case rims, recoil harshly, and batter the rear trunion.
2) it appears to me the front trunion was brittle, or soft. Brittle could cause a sudden fracture and blow out, and bolt engagement face wear …. Which you have…. This will lead to increased head space, and violent blow out. Soft would cause trunion engagement face wear and thus again increased head space and a similar blow out.
I suggest every enthusiast has head space gauges and check periodically
Yea, bolt wear is something else. It kinda gets 'run in' but the weak faulty metalurgy is troublesome indeed. Trunion cracked and coused excessive wear on the lug in just 20 rounds.
Double feed or poor headspeacing broooo
@@smooth247fyi brooooo. No. Bad or excesive heat treatmen. Lol.. ppl thinking headspace gets bad over night. Strong thoughts..
@@knedlops. same difference
@@knedlops. I totally agree with it being improper heat treatment on the trunnion. Sorry about your rifle..glad you didn't get hurt. You can see it was getting beat up from those last rounds that's strange to me, I hope you can get the company to replace it, let us know what happens.
Great video. Fractured trunion. Looks like a wall hanger. Hopefully all of your furniture and gear will transfer over.
I would attempt to send the rifle in, and I would send them the link to your video. Helpfully showing them the failure. Then I would make a follow up video as to your experience with Zastava CS. Subscribed to follow along. Hoping zastava sees this as an opportunity to show off their CS with your growing TH-cam audience.
I have two of their rifles, heavy but dependable.
It will make for some impressive wall art yea 🙂
I’ve run mine with an Ase Ultra 7i suppressor using surplus ammo, the gas return was so strong that the cover lifts up. Now I have to figure out how to reload with less powder, I’ll remove a few rounds and reload them with half the powder charge and then increase the charge gradually in 2 grains increment. I hope Zastava will replace your gun. Take care.
oh Sh*t, that's scary man. Glad you're ok
I've seen several AKM pattern rifles destroyed using similar setup at the range I used to work at.
Ask Robski from AK Operators Union…
"that is properly F*cked" - that about sums it up there, brother!
Yup. She's done for
I will say it does attest to the the quality of the AK design that even with a catastrophic locking lug failure you where utterly unharmed, it failed horribly but safely.
Yea, that it did. I love the design and feel of the rifles.
Yugo/Zastava have always been JUNK! Worst AK variant!! They've ALWAYS been unreliable because they aren't properly copied AKs and have all their horrible gas BS issues.. They're a disaster!! Lol
@smooth247fyi i love your overconfident tone. We have very different opinions tho..
@@smooth247fyi Wired, My M70 has run great for a solid 6 years and by my guess 10k or 12k rounds?
By all means lemons happen in every production line, and its possible some MFGs have more QC issues than others, but for the vast majority of people who buy an off the rack M70 or M92 it will work perfectly and for a very long time
@therideneverends1697 That's simply not true though... Their QC sucks. They have runs and runs of poorly manufactured aks. They aren't modular, and some are almost so off pattern they almost aren't even aks (probably why they're junk)... Every single gas modifier is super prone to fail, causing tons of malfunctions. This is on a large scale. No doubt, worst ak variant.
What year was it produced? I've heard that an early batch had problems with heat treating
By the serial number it is 2012. These are de-milled for sale to the civilian market.
Damn that sucks man! Sorry to see
Thx , appreciated👍
Man that sucks. Glad you’re safe.
Thanks for sharing this. Glad your OK. Could of been bad.
Thank you!
Zastava will probably blame the KNS piston and suppressor ,,in their mind their OEM piston and everything else is made to perfection..
Not a lot of time on range, nor firearm owner, but here in Serbia a lot of gun owners and shooting range folks complained how quality of Zastava has dropped unless it is for the USA market. Complaints range from pistols like the CZ99 to rifles. On some models that were meant for precision and hunting rifles, the accuracy is substandard. Send it to Zastava and bug them to figure it out, but don't expect much.
Interesting. Production year on the rifle is 2012. Looks kike a metalurgical faulure. So ething went wrong at the trunion tempering stage.. Neki lik u fabrici je žešće zajebao 🤣
@knedlops. Yup. That's the same era we (US) recieved 💩 Zastavas
@@Vyacheslavvvv If I recall correcttly, that's the year Zastava increased production which meant hiring more people, so very likely someone didn't check what the quality of the new guy's work.
I know with zastava USA at least if you put any aftermarket parts whatsoever in the rifle it voids the warranty. If you are going to send it in try returning the rifle in its stock configuration
Nothing a hammer and some JB Weld can’t fix.
🙂
Thank you for making this video, I’m sorry that this happened thankfully you were not injured.
Could you make a follow up video showing the barrel without the hand guard on, curious if there is any bulging in the barrel.
I wonder if a squib round followed by a normal round pushing out the stuck bullet in the barrel created overpressure and thus shearing the lugs on the trunion and bolt.
Because of the camera angle when you were training I could not see if all the shots impacted the targets or dirt backstop.
Thank you again
No problem, happy to share experiences with the community. No squib ,no bulging, barrel is fine. The rifle actually chambered the next round but didn't go into battery.
I will make a follow up video for sure!
@@knedlops.Are you in the US, as some people are curious if this was imported though Century Arms or Zastava USA? Also does the ammo you used come sealed in the metal surplus cans or how is it packaged ?
PS, been watching some of your other uploads; you are without doubt a skilled shooter.
@Wolf_Avery Thanks! I am from Slovenia, live here to. The rifle was not a us import. Was bought here. Usually, came in batches that were demiled for the civ market straight from the Zastava factory. Ammo is presumably chineese or Eastern EU copper coated surplus
Comes in cardboard boxes.
I'm glad you are a-OK. Greetings from Hungary and I hope you'll figure it out.
This has been happening with others with Zastava. My theory is the metallurgy is bad or it's bad heat treatment somewhere in the process.
Otherwise, I'm glad you are ok.
Subscribed and hope to hear more on this.
Seems to be the metalurgy. I've been sent numerous pictures of exact failures.
@@knedlops.You're getting pictures sent to you of broken zastavas?
@jamesjams5085 yes, all of them with the same exact failures
@knedlops. A friend who lives in Bled told me that arr quality Hungarian made AKs that were ex Slovenian army being converted for sale to civilians. Find one of those. Good luck.
Man, I'm sorry to hear this.
From one Zastava owner to the next, this is a very rare thing, I don't know if I have ever seen a Zastava M92 blow like this. The M92 is a well built firearm, this one obviously was a tool that slipped through the QC cracks or something. I've heard of M92's putting down 10k rounds and still having plenty of life to them so to see yours blew up on you is pretty crazy. Im wondering if there was something off about the bolts rotation that may have caused a out of battery discharge. Idk hard to tell. Ide get in touch with ZastavaUSA and explain the issues I had, I feel like they would take care of you, however the suppressor may draw problems idk. I run a 4 piece flash can on mine, not a suppressor so idk the fine print on and kind of warranty it might have.
But im wishing you the best.
If youre to disheartened to buy another Zastava, I would highly recommend WBP. You can get a milled mini jack off AOA website for a good deal. Quality AK's from Poland.
Thanks. Not in the US. This happened in Slovenia. The rifles come from Serbia and are then converted to semi auto for sale to the civilian market. Totaly different than Zastava Usa. I am not interested in rebuilding it. Keep it as ut is because it has sentimental family value.
I did run it with a traditional suppressor with tuned gas... add an over heat treated truinion ,shoot a lot and you get it to blow.
Good luck with getting some analysis on the failure! Glad you are ok.
Your English is very good, bro.
Thank you
Your English is Pretty good, looks like bolt was slightly out of Battery when it fired?
Thanks. Bolt was out of battery but not on the last shot. Last shot was fine. I remember seeing the shot on the tatget and getting a triggerslap ,proceeded to the next target and was out of battery but still chambered a round.
I'm from the US, what are gun laws like there? If Vepr , Saiga, Norinco are available I'd go with one of those.... No longer imported to the US... We were getting parts kits from Slovenia ( new Manufacture) heard they were good?
Think the parts kits were from Kohl Arms?
Maybe id try not using surplus ammo and that suppressor together on the same rifle at the same time ever again.
You have my condolences!
I think your gun worked itself out of headspace. It’s not worth fixing unless Zastava helps you. Which they should in my opinion, replace it completely. You should get a set of field gauges to check headspacing. Good luck my friend I’m glad you are ok.
Thanks! But, yeah.. either that or just over treated trunion. No point sending this to zastava. They wont touch it if modified.
Looks like an out of battery ignition. Do you have the casing? Did you pull the trigger, or did it happen when the round was chambered?
It was in battery as far as we can see on the video. No puff ,i only remember getting a trigger slap..
Looks to me like it may have been caused by a round being fired before the round was fully seated in the chamber...
Like others have said, and most importantly, you’re ok & unhurt. I have the exact same gun, also running suppressed with a KNS. I’ve only recently started suppressing mine so I don’t have as many rounds with a can on as yours has had but I haven’t seen any damage like yours has. It looks to me like an out of battery detonation but why is what I can’t figure out.
I hope Zastava can help. You’ve got my sub & I’ll be watching how this works out for you with great interest.
They're great rifles. I believe this was a batch of rifles used with excessive heat treatment. Making the trunion brittle .
Enjoy your gun👍
Under gassing can cause this malfunction. I started to have bolt hang up issues on my 92 and was worried the KNS was going to cause an out of battery detonation, so I added more gas and it doesn't hang up anymore.
@@dantimmerman6693 valid point my man. I had the same worries, but the bolt never got close to being able to detonate on a hang up. It was just full mag hold ups. I ran it with enough gas to run properly but not eat it self.. ironically 😄
That's better broken at the range... than when you potentially really need it right? GL
Sorry to see that happen. but the algorith has smiled on you. Subbed.
🙂 thank you!
I subbed because I want to see a update on this. I hope they warranty it 🙏
Zastava butter steel strikes again
Sorry for your loss man. I’m glad you were not injured. Your English is more than fine. Hopefully Zastava will help you out. Was thinking of buying an M85. Interested now. Subsscribed
ZSR ammo strikes again.
I had an out of battery explosion with my WASR 10 that swelled the receiver like yours. Not saying it was his fault, but I showed a friend how to use my Slidefire stock when they were legal over a decade ago. It happened during a burst. It wasn’t suppressed. There was an odd bang at the end of the string. It blew the dust cover off even. The bullet case was still in the receiver, but not all the way. The right side of the case burst open. My receiver was swollen too. The bolt still would manually cycle, like a good AK would, but I never shot it after that. I don’t know what caused it. Rapid fire, primer issue, firing pin sticking, feeding hangup problem or whatever, the bullet ignited out of battery before it chambered. I wonder if you could find your bullet case to inspect it?
Interesting.
Case seemed fine..
What year was your WASR manufactured, roughly? You're probably aware of their pitiful QC until 2011 or so
@@Vyacheslavvvv I’m not sure. I sold that gun to a friend for strictly a display or prop gun for videos. I’m not even sure that all the numbers matched from bolt to receiver.
@RangeToyz glad you're ok after the catastrophic failure. At this point, I'd rely on just about any Romanian or Polish built AK than [Serbian] Zastavas. Their QC has gone downhill substantially in the past 2 years but more appalling is their dismal metallurgy techniques.
Just saw a thread where someone could physically bend Zastava's truntion with pliers whereas he couldn't with Bulgarian, Romanian, Russian, or Polish. To add, a gunsmith noted his yugo reciever refused to (weld) flow well with filler & welding without porosity was impossible
Fourthly, when Zastava trunions break, they tend to crack & explode along the entire reciever. Unheard in the other aforementioned producer's firearms
@@Vyacheslavvvv that’s crazy. Here in the USA, demand is way up on guns and ammo due to political propaganda and the gun industry and rifle ammo prices are double to triple of what they were from four years ago. I’m getting back into 22LR guns now because that ammo has basically stayed the same.
Glad you are ok dude, it is kinda sad this to happen to a zastava rifle. I think its bad material being used in your rifle.
If you are selling the can tell me, im from MK
Pozdrav
You have an old NPAP with 1mm receiver, not the newer ZPAP with bulged trunnion and 1.5 mil receiver.
Bulged receiver on a m92 has only been made for the us import. Bulged receiver does not make a better or stronger trunion. It is there to prevent bending of the receiver due to the high recoil of using blanks to fire a rifle grenade.
Yeah you got to watch those PSA rifles. Never received one without major flaws.
Not a PSA.. this wasn't an import to the US. This happened in Slovenia. A place you've probably never heard of.
Always, and i mean ALWAYS periodically headspage gauge your rifles.
Trunnion broke. It's a non bulged trunnion. So an early m92. Do you know who made that AK? Possibly a cast trunnion looking at it. Is there markings on the outside of the front trunnion? You may of had a bad round not go out the barrel and next round blew it up. Happened to me using Igman ammo but my next round wouldn't chamber thankfully and I knocked out the projectile w/ my cleaning rod. It was bad gunpowder in the Igman ammo I had bought.
Zastava Kraguljevac made it.
They're junk aks
Correct. The later models are great actually
What kind of were you using at time of detonation? Do you have headspace gauges? After 3 thousand rounds i start Checking head space occasionally just for my own curiosity. Suppressed fire puts more pressure on parts or no? I dont know much about suppressors. It is a mass produced item.lemons occasionally sneak through unfortunately.
I don't have a go/no go gauge, but I am quite sure if it had a headspace issue, it would be visible in some earlier bolt and lug ware..
Nyet comrad. English is fine. Rifle, not so much. That was a metalurgical failure of the trunion. That particular failure originated as a structural failure of the front trunnion from full battery. I have seen one cast gun explode nearly identically. The cast guns are so soft that they usually just bend and stretch, or wear abnormally. That gun had other problems. . . It could also have happened this way to a gun with a forged trunnion if it tempered too hard. In this case, with higher round count, I think likely one of several things or combination of them likely caused this. Your gas system has nothing to do with chamber pressure. 1 headspace may have been on the tight side. 2 you may have had a very subtle anomally in hardness of the front trunnion. You could check this by dimpling an undamaged area of it with a rockwell scale and comparing to a known spec. 3 you had a defective round somewhere along the line that had too long a neck and caused a pressure spike that damaged the trunnion. You will likely find evedence of a material related failure in OAL length of your fired casings growing over time; rapidly when leading up to failure. This is due to growing headspace, which can cure neck related pressure spikes, batters itself over time and worsens.
It looks more and more like it got over tempered, making it brittle. I checked empty casings on a regular basis to check for abnormality, dinted casings and such, but since the kns i haven't been seeying anything. I have cca 1k of brass s&b casings looking perfect. Thx for your opinion.
@knedlops. One symptom to note that isn't always immediately obvious is stretch rings. In some brass, they can be hard to see, and other brass very obvious. If you were checking case OAL with a mic, you would've seen that dimension elongate slightly, but most of any change would occur in the last few rounds before failure. They can occur anywhere forward of the case head, usually forwards of the thicker portion of the case wall, and aft of the bottle neck, but can also form on the bottle neck (shoulder) itself. You may also try to mic the base of the cases, just forward of the head, and see if you can detect any bulging that is beyond normal. Due to the cases taper, this can be a good early warning sign, and I see it a lot in 30-30 marlin 95 pattern guns that go out of headspace, usually coupled with backed out primers. The latter won't be present if the primer pockets are staked and the rounds use hard military style primers, but may have a slightly shallower pin dent with a slight lip around it that will sang your finger nail. If you reload with a manual press, these will feel just a bit harder to resize. If one doesn't have a micrometer, you can check this with a steel straight edge ruler held lengthwise on one side of the case.
I will note that I had heard of QC issues with Zastava's receivers in the last couple of years, but nothing about trunnion failures. I think this is a testament to the ak. Even in the event of a catastrophic breech failure, you were still protected.
Dang I just bought a m90 and the rear trunnion has started settling because the receiver button is stuck like glue!
Keep an eye on the fron trunion.
Are you sure that's ZPAP M92? Looks like just a PAP M92, without the RPK trunnion and 1.5mm receiver.
On the plus side, those beefy lugs and trunnion kept your kaboom from becoming a trip to the hospital. Even with the KNS tuning, failure due to suppressor back pressure probably isn't covered by Zastava.
Let us know if you get gunsmith quotes for repair. Kind of curious in case something similar ever happens.
Zastava voids it's waranty if you look at it sideways.. anyway im not stateside. Zastava in Serbia would just laugh if I send them the rifle.
@@knedlops. Sorry for you brother. That's a major letdown. People in my circles love Zastava products; sorry that their Customer Service can't or won't help.
If a gunsmith isn't really an option & you're decent with machine/tool work, you might be able to repair/replace the receiver damage yourself. Removing the rivets and getting a better look at the damage would be a decent exercise in any case.
is squib Mabe? Possibly headspace way out?
Did you find the bullet casing ?
I have seen home reloads blow up guns but never surplus
Not ammo related at all. Bad material, microfractures. Looks like a cast trunion fail, but Zastava makes forged trunions. No casting marks.
I’ve never seen that happen before. I was thinking Mabe the headspace might have gone out of wack?
I’m definitely interested to see what the cause was
@@forthehellofit5544 nope.. the gun was fine.
Heat treatment issue even with a hotter round there shouldnt be that much gauling and peening if hardness was tested..
It was a catastrophic failure when it was new! IMHO
Almost funny 😁
Old English rhyme --It's the same the whole world over and it's a crying shame, it's the rich that get the benefit ,it's the poor that get the blame..this case in a nutshell.
Even if you do get a new reciever and trunnion you dont even know if headspace will stay the same. If not, that would mean new barrel possibly new pins for barrel population since its had less than 7k rounds i wouldnt be suprised pins are bent after pressing out. Rather get a new one at this point.
Yes. All true
Time to buy an Arsenal or Saiga
Headspace issues how many rounds thru her and what type of adjustable gas system do you have ironically if its not a bleed off type it creates higher chamber pressure you may have been overheating the trunnion causing bowing and an out of battery detonation you need reciever and trunnion parts are all over unfortunately expensive and rare a new gun was cheaper than building it through all my research in the last three days
Yup, no point in rebuilding it. Especially not here in europe. I had the KNS on set to a functioning but not overgassed setting. There are numerous cases of a trunion fail, just like mine.
Damn. That sucks. Maybe something wrong with the round (too hot, too large of bullet).
Nope, bad metalurgy, excessive heat treatment .. was not ammo related. Gun had a kns system set to a functioning setting.
Pap rifles- both the npap and even the newer zpap rifles- have been listed on the list of variants which are not recommended in the main Facebook ak groups for awhile now due to subspec metal hardening- they often test as soft and sometimes even brittle- there doesn’t seem to be a standard. Get a WASR if you want a quality import.
This is 2012 production year. Zastava didnt import their guns in to the US as they do know. This was made for the mil market and then converted to be sold to the civ market..
But yea.. as you said. It has to be the material.
Paul Popov has pushed this narrative for years and never once followed up on requests to send the actual data to the group. If you request the data, he will ban you. The AK Facebook groups are not a reliable source of information.
Wait wait wait ....😮😮😮 what stock adapter is that ??? It has a picatiny rail ?????
It's A TDI underfolder to pic adapter.
THANK U @@knedlops.
Zastava AKs are reversed engineered. They never got the TDP from Russia. They're fairly low quality, one step above Cugir.
That didn't just happen. The bolt lugs & trunnion showed deformation for quite a while.
Yeah sure, just change some vital components of a gun with aftermarket ones and use ammo, suppressors and other stuff not recommended by manufacturer.
And than when stuff like thas happens, wonder why it happened.
Sucks that you had to encountered this, unfortunately. But you are safe and well! Also, why kind of part do you used to make your underfolder, able to use foldable stock? Thank you!
A TDI underfolder stock adapter and a sig folding mech. Good stuff.
What ammo?
Powder type and load?
What casing and bulet weight and type?
Bad iron casings that prevented good lock and hot load whit bad supressor that owerpressured the system.
Listen to the sound of the gunshot, wery crisp and loud for a supresed shot.
I have a Zpap 92. I'd be pissed off if the same thing happened to mine.
Keep an eye on the ware of the locking lugs, inspect friction points.
@knedlops. I only shot 1200 rounds through it so far. Most of the catastrophic failures I read online are around 5k for the zpaps. Hopefully, mine can last at least that long.
Zastava has been known in the past for metallurgy issues.
Everyone who owns an AK should have go-no go gauges.
To those saying its not a ZPAP doesn’t ZPAP stand for Zastava PAP (Polu-automatska puška/pištolj,) “Semi-automatic rifle/pistol" ?
No. It's just the letter that pre fix the pap describing the Gen. Zpap is the latest Gen...Opap, Npap and Zpap 🤙🏼
@@ComblocEliOk cool, thank you for the insight.
@ComblockEli No. It is an importer nomenclature. Official Zastava nomecl. is prefixed with a letter M and then the year it started production followe by PAP. Pol avtomatska puska .
@@knedlops. So each generation 😂
Sounds like headspace
Bolt lug was only contacting one side of the trunnion looks like to me. Had a Galil clone doing the same. Suppressed makes it worse on the back pressure too IMHO. Cheers!
Your English is better than mine 😂😂👍🏿👍🏿👍🏿
That shit sucks ...I blew my AR up a few years back also still don't know what happened exactly but maybe it was a Failure to extract the spent round ruined my day this is when I learned the laws of guns .....1 is none and 2 is 1 so I bought more rifels incase of failure.....🙄
Can't argue with logic. Good man.
Subbed
Thank you!
This is terrible news. I am sorry for your loss of your only rifle. Those rifles have a rugged reputation. Could a squib load been followed up with a hot one, under full auto shooting?
No, it was bad metalurgy. The front trunion started cracking around the locking lugs. Excessive heat treatment most probably.
@@knedlops. Thank you. That does make sense. I am subscribed. This looks like an interesting channel. Be well.
@@FrankieJizking-js3yv thx. There will be a follow up video.
Damn shame hope u can get it fixed man
Lots of people apparently have been having issues with new zastavas lately as well , apparently mainly lots of qc issues from what I understand not sure how that happened to your ak but glad it didn’t blow up in your face and cause damage to ya
Thanks, appreciated. The receiver took the most of the explosion and held together like a champ.
This is the first I've heard of any systemic problems from Zastava
@@jamesjams5085 feels like I opened a can of worms..
Wonder if the peening on the locking lug was the cause, or just a symptom.
Overpressure would peen, but also a peened locking lug could cause the breech to unlock too early and dump excess pressure outside the breech.
Are you able to check the cases of the rounds fired that day for signs of over pressure?
th-cam.com/video/YgHEtLL10ZE/w-d-xo.htmlfeature=shared
How many Zastavas do you own, and how do you feel about them now? Thanks for the video glad you're ok.
Thanks. Just the one.
Could it be because of the ammo?
Spicy and over pressured ammo for a longer time.
But that's only a guess.
Also the amount of pressure and smoke puffing out of the ejection port felt too much. (perhaps because of the silencer?)
Again I'm not an AK guy but I just spoke what I felt about your video.
Yes, the gasses on ak's when suppressed exit through the port and down the magazine and the trigger . Little to no gas in your face.
@@knedlops. Thanks for the info.
Glad it wasn't anything serious! Do you know how many rounds you put through it?
Nothing serious? The whole receiver is fucked.
Just at 7k rounds
I wonder if Century Arms would be Zastava's excuse! Looks to be an older model
Hah. Who knows 🙂. It is an older model. No boulged receiver. Note that a boulged recever is not there to save bad metalurgy..
RIP m92 I hope you get a new one
I don't know how things are in Slovenia, but in the u.s. there are alot of great receiver options. Childress guns out of West Virginia has a yugo pattern receiver for about $100. Not sure how the export laws would work. But if nothing else it's something to think about
Oh this wouldn't be a problem to rebuild in the US. In Slovenia.. a different problem. The Zastava factory however.. is not that far way
Vary interesting
Maybe you had a round that was over charged that caused it
No, I would notice a spicy round. All I got was a triggerslap on the last cycled.shot. We also checked the video.
Dam that’s sucks man
Did anyone have access to your rifle who could have switched components on accident or on purpose?
Just spit balling here...
No, no one. It's kept in a safe.
Most firearm failures are from the operator and mods they do to them. Never once have i have any problems with my firearms but i don't do crazy mods on them as well i keep them mostly stock except for optics or furniture.
I see where you're coming from and there is truth to that. But not in this case bud.
@@knedlops. I defn understand. Is why i said most and not all. The failure you had looked pretty bad. Did you ever figure out what caused it? overcharged ammo? or headspace issue?
@@knedlops. Btw i subbed, Defn wanna see more videos. Awesome stuff
@@MrLex87 thanks, appreciated a lot
Call zastava and see what they can do for you.....thats a shame!
Looks like out of battery detonation imo.
you did well
LEAVE THE AK ALONE LOOKS LIKE ITS BEEN BACK YARD JERRY RIGGED
@kneslops Yeah I can't see how that happened either I don't think you did anything wrong I think that maybe your front trunion must have had some defects in it when the gun was assembled that nobody knew about and it just blew up. I saw your video of your shooting and we would have noticed a heavy recoil on the shot that blew it up if that was the problem. Send the gun back get a new one. If you don't trust them anymore sell the new one after you get it and go buy a different one. Set it up like that. I noticed it doesn't have a bulge front trunion though? Also does it have a 1.5 mm receiver? Let me know even though I don't think it would have blown up if it was built stronger but I still think it should have not blown up no matter what. Thanks and good luck brother. P. S. Hey at least it didn't blow you up while it was blowing itself up! Still a bummer though
Thanks, appreciated. M92's don't use 1.5mm receiver. Only after 2016 or something they added them to the m92 for the us market.
A superpower could not manufacture a quality ak47 that could match the quality of a cheaply made AK47 in a third world country. 😂😂😂😂😂😂😂😂😂😂😂
The receiver, trunnion and bolt are history. Its not really worth salvaging. I don't own any zastava guns
Yup. It would need a complete rebuild with new trunion, bolt too
I'm a little confused my zpap m92 has a bulged RPK trunnion and I noticed yours does not. Maybe it's a old one I would contact them but Zastava has been making them the M92 M85 and M70 all with bulged RPK trunnions at least for the last 5 years maybe 6. Very curious
M92 with a bilged trunion are made only for the us market. Even those blew up sadly..
@@knedlops.Regarding US M92s exploding, source? I've never seen such instances in all the forums I purvey
Source was Reddit,. Take it for what its worth but there are images of simmilar blow ups not just zastava.
@knedlops. using different keystrokes, I found what you're saying. You're right; Zastava metallurgy is rubbish. I'd wager their 1.5mn (US) trunions are more of a band-aid rather than a justification to "strengthen" their recievers to incorporate stress tolerances when firing grenades, (something Yugos cared about & Russians didn’t).
Even Romanian & Polish have better metallurgy techniques than (soft) Serbian Zas. Shame on them
Extremely high chamber pressure..blocked barrel, suppressor blocked or a defective round that was loaded way too hot. There also the possibility you acquired a booby-trapped round that when fire destroys gun and maiming the shooter these rounds are made by different government. These rounds are left or supplied to the opposition force secretly by different means to wreak havoc on the opposition force by maiming troops and damaging the guns using the exploding bullet!
Nah.. watch the video 🙂👍
was that pistol maintained as it should have been?
Good maintenance, competition gun, regularly cleaned and inspected.
You do not suppress M92. It suppresses you!
😀
Npap and opaps have soft recievers
Soft would be better in this cas. This was excessive heat treatment, making it brittle.
