- Welcome back to another episode of Total Recoil with our Gun Expert Paul Meixner and our host Israel Wright reacting to the various guns of Call of Duty: Black Ops 4. In this video, Paul and Israel go over several of the games' most used/iconic weapons whilst analyzing each and identifying stand-out characteristics, and comparing them to real-life firearms. Also, bonus, learn how a silencer works on a gun, I was very surprised. We hope you enjoy today's video :)
The first-person shooter video game Black Ops 4 is part of the Call of Duty series. The first entry in the Call of Duty series without a traditional single-player campaign, Black Ops 4 focuses only on multiplayer, Zombies, and a new battle royale mode called Blackout.

Paul's actually right on the money! The Russians developed multiple firearms that are designed to be used underwater, though I believe he's talking about the APS. It was designed for anti-frogmen tactics during the era of the USSR
And batman gave the US military shark repellent
Nerd 😛 alert!
Is that the same gun that was featured in CoD Ghosts??
@@toxic_ramen742 knowledgable
@@diehardernxgt2161 Yeah.
Me: *draws something vaguely like a gun but looks more like a banana with a handle*
Paul: "Oh yeah, this is based on the Bananaramaweisse VQ91 since it has that magazine ejector that's shaped like Dave Geohl's head. Now I personally don't like the telekinetic reflex sight, it just feels a little awkward in transition, but the younger soldiers in Vanuatu's military prefer it for it's sturdiness and that it makes the bad guys do the Texas Two-Step before they die. All in all, good quality gun, but not good for beginners or for people with acid reflux."
This comment was absolutely hilarious.
@@CorndogCrusader I'm not a guns nerd so that's what gun talk sounds like to me but it's so interesting

The AK that the dude is talking about that is specifically designed to shoot underwater is called the APS. It's pretty badass.
I need to go look it up now
Russians where like: Bly*t whe must shoot the shark.
Wasn't it featured in COD Ghosts during the mission to sink a ship?
yeah, aps was created in the 70s they're constantly improving it and revamping and i think now there's a newer model/variant thats in mass production or that was the plan a while back
BTW it wasn't designed to "kill sharks" but enemy divers.
Woods: "Don't blackout, man, I'm on it."
I hope one day we get the the Campaign that was scrapped during its development of BO4.Like Leaks are COD 2023 is made by Treyarch and it's futuristic .That's why we have those cutscenes in BO4 Specialists HQ.I hope this becomes a reality one day.
One thing that I'm worried is QA tester back in 2018 said it was like BO3 Campaign.🤔
@@ChandranPrema123 I held out on buying Black Ops 4 for almost the entire year it released because it didn't have a campaign.
@@ChandranPrema123 bo4 won’t ever get one because they never had a proper campaign. They had several smaller versions but not a fully fledged campaign
I feel Israel is more dad out’d with this guy compared to Cameron.
They look like they would be hanging out by the grill instead of around anyone else
Israel definitely isn't a gun guy. he used what he was given but didn't really care about what it was. Cam on the other hand...
Cameroon is his son who is just 10 years younger than his Father Israel🤣
"Well thats because you where Special ED" "Yes" "I mean Special Op".
That look to the side fucking killed me. Just the, all right you got me on that one...
4:02 That's a lethal equipment which can be used in close quarter combats. (not usable in the game tho it's just the weapon model)
So like a tiny nightstick?
What was it supposed to do?

0:00 5:08 “Handguns put holes in people, rifles put holes through people, and shotguns tear chunks of *duck quack* off of people” great quote
Now if you can tell me who originally said that...
And Explosive Blow Chuck duck off of people
Triangle bullets were kind of a failed attempt of making a gun with more ammo capacity, but yeah... failed attempt still xD
Edit: I love they mentioned the Spanish CETME, it really did make a reference for H&K, it wasn't the best gun in the world and most of the soldiers hated it for it's weight on early stages but still it was a good gun. Loving they mentioned it.
HK was formed by former Engineers of Mauser. So HK is basically the Heir of Mauser. CETME was a spanish Project but done by german Engineers from Simson and Mauser. They used the late-war Prototype StG45 as Groundpoint which resulted in the CETME which later resulted in the HK G3 one of the most produced Guns worldwide. All three Models can track their Roots back to the StG44, the first real Assault Rifle.
@@ArtjomKoslow Not only that, but Heckler and Koch were also former Mauser employees that went back to the Mauser plant and kept it running with civilian items until they could make guns again. When they hired the CETME team, it was tantamount to a family reunion.
They're called Trounds! They actually do allow you to carry more ammo than traditional ammunition as they're more space-efficient. They are hard to make precise enough to get them to feed consistently so the concept was quickly abandoned.
Actually those triangle bullets are trounds and we're supposed to be used in high fire rate machine guns with a open revolving cylinder system
To test this the dardick revolver pistol was created it was using cylinder and magazine at the same time
He tested it to make more space efficient ammo with the highest fire rate possible with one barrel
Pretty interesting stuff
What made the system fail? Was it the hinged belt system? Was it to heavy?
Edit: @matthew blackwood thank you
3:05 the hk slap is actually a part of the manual of arms. It's the way hk wants you to close the bolt to ensure gun goes into battery.
No it isn't and you'd get shit for it in the HK-equipped militaries because it degrades the bolt catch notch on the receiver. And that's not a separate part, it's cut into the receiver and when it wears down and can't hold the handle anymore, the gun becomes unusable and you need to replace the receiver or at least weld it back up. It's still a cool-looking move and is faster than properly letting down the handle (not by much, but still), and if you're a high-speed low-drag operator (like most of HKs customers in US) you'll burn the barrel out faster than you wear the notch down anyway.
@@BlackBladeGroM It IS part of the official manual of arms as posted by HK.
Most militarys that use HK weapons however use their own manual of arms, and THEY are the ones who tell you not to do it. Makes sense, because they will try to use the same guns for a lot of soldiers in succsession (The degrading of the catch notch is minimal when we are talking about a gun for one single person, but if generations of soldiers are doing it, you will of course get some wear and tear)
That Hellion looks like it has way lower velocity than a 40mm. Strange that it has any range at all.
I think it is a gameplay balance thing, to give a chance for players to dodge it.
The hellions rockets curve in unexpected ways too
@@kixakii436 When dumb-firing yes, because it's mainly made to lock-on to vehicles and drones and stuff. It's not really made to kill players (I think you needed 2 shots to kill a player anyways, IIRC, haven't played BO4 in a good while) although it's doable.
They should've seen the Hades LMG lmao, it's like the Finn LMG and the Bizon had a son
Nope its a bizon and m249 saw or a north Korean bizon/ak
Theoretically, a triangular cartridge can pack tighter than a traditional cartridge in a magazine or layered belts, but, well, they don't have the belt set up to take advantage of that. And it also isn't a huge difference in the first place.
So when the little pointly stick on the MX9 is pointed out at 4:00, turns out this is a CQB Mute Stick, described by Will Huang, who describes himself on Artstation as a Principle Artist. It's used for when you're close to the enemy. Put the weapon close to your body while your rifle hand moves to the Stick, then unlock it from its place and start jabbing away.
Will Huang also explains the Outlaw as its cylinder being a brass holder where the used rounds go to after being used.
Thanks man! Always wondered what it was. Don’t like it at all but at least I know now
The Cordite reminds me of the Halo 2/Halo 3 ODST SMG. It also loads from the port side of the weapon. Though, with both, I can see the P90 resemblance, with the "slapstick" mags.
The Koshka definitely doesnt give a flying damn about "more moving parts means more places for sand/dirt/dust to get into"
Same goes for the Outlaw.
But aren’t revolvers in general pretty reliable? Idk I’m not a gun guy but I seem to recall that. The bolt on the Outlaw might overcomplicate the design though.
@@eyywannn8601 they are reliable but introducing a bolt into the mix and yaving open crevices and gaps allow for things to get in and gunk em up. While they don't jam, they still have a very low capacity for what is needed in a modern combat zone. That's one of the main reasons we phased out the .38 Special for weapons like the M9/92FS. Even other slide pistols like the M1911 ended up getting phased out by the M9/92FS.
Now, were getting to the point where we're phasing those out as well.
Great choice of experts. These guys really knew their stuff.
Idk man, repeating Clint Smith quotes and calling an hk slap a "very John wick" move, when it's literally hks code of arms, makes them definitely seem like normies. I appreciate their service, and appreciate them coming on to influence younger generations who have interests in firearms, I'm just saying I wouldn't want to take a class from these guys.. wouldn't mind cracking a beer with em though.
@@cjlane4465 it needs to be entertainment as well… relax
@@Gh3tt0Gam3r i didnt say it wasnt.. you sure you read the same message? Can entertainment not be accurate and entertainment at the same time?? Saying an hk slap is "john wick" isnt entertainment, its ignorance. But please, go off.
The Russians made underwater rifles for engaging enemy frogmen. Because before that they had to engage each other with diving knives.
7:47 it’s called the APS underwater rifle. It looks like an Ak an walrus like an Ak but it shoots harpoons or something like that.
it doesnt shoot harpoons lol
It's just shoots very long bullets.
@@sciarpecyril basically
@@sigsauer_firearms I dont fuckin remember they look like mini harpoons I didnt say they were.
@@vincentmartineau2006 "it shoots harpoons or something like that"
The Russian developed the APS rifle mainly for underwater frogmen on frogmen engagement because back in the day frogmen are only equipped with knife
This new gun expert seems much more knowledgeable on firearms than the other one was.
Im glad Im not alone with my opinion on the MX9.
Assuming its some prototype SMG, it does have a weird rail sight and I don't think many modern sight attachments can on it. It also has this weird nail-like thing on the right that makes not much sense and purpose on there.
Apart from that its a good meta weapon in CODM too.
Anyone know what that weird thing is? At first I thought it was the charging handle when I first played it but it’s obviously not.
@@afd19850 according to other comments its basically a metal spike that you can pull out and use like a knife. not usable in game though
Love the combination of these two! Please do more videos of them when you can!
Love those vids, keep doing it❤️
Yes indeed,
the Soviet Military developed a Firearm, specificly for the use underwater - not sure if it was to be able to shoot sharks or not, but doesnt change the fact that they did.
Its Called APS Underwater Rifle, and was developed under the guidance of Vladimir Simonov from 1970-1975.
Chamered for special 5.66mm Rounds with a wierd Boxmagazine, im not sure if it becomes part of the "foregrip" or the "foregrip" is part of the mag, but it certainly looks different then assembled.
Open nonadjustable sight, which look a bit like Fallout 4 got thier inspiration for thier Pipegun sights not gonna lie - but knowing soviet tech it somehow still worked.
The rifle had a longer life expectancy underwater than on the surface (around 2000 shots underwater vs 180(!) on the surface).
as far as i am aware (and i litery only know a few things about this gun) it was only used by Combat Divers and special units of the russian Navy.
Gunnerd brainfart over - you can go about your buissnes again.
Srly go away nothing to see here.
if paul is interested about the russians having underwater weapons to kill sharks, he should see the one used in a call of duty ghosts mission which is the one with the fish ai
If vanguard is out, both of them need a therapy after reacting to the guns 😂😂
Gamology u gave me heart for saying „let them
Do Tarkov“
Iam so hyped !!!
Edit*: Hunt showdown too, please.
Yes Tarkov!

No Isarel... No... it doesn’t work like that, you either have a cool mohawk or you don’t have one, I understand you

Never saw this one coming, I've been playing this one a lot lately
On console? I quit the pc version because of hackers, was a fun game and miss it
Beretta 93r is semi auto or 3 round burst fire mode only. Cordite is basically p90 turned sideways with a belt fed modification. A modern villa peraosa 9mm machine gun from ww1. The lmg is a hybrid of g11, lsat and trounds. The launcher is based on m202 flash.
there is 1 full auto 93R, the green titanium M93R. th-cam.com/video/HjH1yk2duv4/w-d-xo.html
@@Swogfish Well I am talking about most production ones.
that "handguns put holes in people, etc..." qoute is from the guy that runs Thunder Ranch. He's a vet, super cool dude
He is super cool! I mentioned Clint Smith and Thunder Ranch in the video but unfortunately it ended up on the editing room floor. Thanks for pointing it out and helping to protect Clint’s legacy!
The bald dude has a LOT of knowledge.
This was an awesome idea, yall should do some more!!!
nice to see you again paul !
11:14 I watch Forgotten Weapons too! Would think there would be a watermark or something. The blue triangle bullets can be found on that channel as well. They are a patient housing used to hold a cartridge removing reciprocating motion of clambering the round.
yes, the dardick pistol and its "trounds"
I like how he half quoted Clint Smith at the start lmao
5:07 That’s one of the main reasons I just got out of COD and Battle Field. You could shoot your opponents with a pistol and they went right down but when you shot them with a shotgun at close range it took at least 2-3 shots and they field you with lead while you pumped the shotgun back.
It's a video game it's not supposed to make sense
Everyone knows it’s a video game but to go as far to make a pistol stronger then a shotgun is just stupid.
Would love to see these guys react to the specialist abilities in blops 3 and 4 and how believable/unbelievable some of them are + maybe their effectiveness in a hypothetical real combat scenario
U could literally listen to these guys talk about guns all day
4:45, nice hand gestures!
😘
Really liking Mr.Wright with Mr.Meixner love to see him check out guns for the Battlefield franchise
The triangular bullets thing is building on the idea that you can fit more rounds into a box magazine or magazine of any kind if they're triangular instead of round
Triangular bullet housings were experimented with awhile ago because in theory, the ammo can be packed more tightly together and fit more ammo. They problem with them is the the triangular housing are too expensive to make compared to a standard housing for the pay off. There is an example of one of these guns on forgotten weapons’ youtube channel but unfortunately, I don’t have the link.
11:00. Fun fact there were actually round tri anguler like that in the 60 called trounds. It was made for this pistol called a dardick and the idea of the dardick was to make a mag fed revolver. Something with high capacity and simicity of a revolver. I dont know why the dardick couldnt use normal rounds but it most likely has to do with reliability.
Great combo both great lads 👍
Fun fact! Some of the first "repeating rifles" were had a revolving cylinder like the kotska and outlaw
Glad to see another video
The HK slap is in the manual for the MP5 and similar configurations, in order to make sure that the bolt is correctly seated forward
3:28
the mx9 rails vaguely resembles the N-strike rails from nerf
I got to shoot our SEAL team's MP5s when we did the ammo DumpEx when coming back from deployment - really manageable recoil if you can account for the climb.
So u get to shoot all the ammo when they come back?
@@gravestone9831 Yes. All unexpended ordnance besides what is assigned to each Marine or SEAL has to go bye bye before leaving international waters and entering American waters. It's a right blast!
Great video and commentary.
The triangular caseless ammo is actually very similar looking to the Dardick revolver's weird 'tround' ammo.
And that revolver was just an attempt to fund a machine gun.
As far as i know that little thing on the side of the mx9 is detachable, iv looked at it up close and it looks like a little torch and the point would be the tool for popping the holding pins out when stripping the weapon, but in all honesty i haven't got a clue what it is but i do know its detachable because of the clip on the side of the weapon that holds it in place..
Shot an MP5A2 on semi, it does have a feel nice in the arms
We need more of theses videos
Also the triangle ammo is indeed CT ammo "cased telescoped" and there was an automatic pistol that had 23 round "belts" in a magazine that used those triangle shaped bullets through a revolving cylinder feed to the firing pin and chamber
Man... this new guy Paul Meixner is a night and day difference to the last guy you had in one of these. This dude knows his shit. 👍
Love the call of duty franchise campaigns are the best keep them coming.
Israel's "Russian" accent sounds more Italian.
🤌
Those Italian Russians again, amirite?
Especially with that hand gesture...
I kinda imagined that the Triangle Round casings that were in the LMG or whatever type it was, Might of been some sort of folding design for the ammo to move with less guiding out of the ammo box? But not sure if it would really save all that much space that way unless they made it much tighter.
Cordite looks a lot like a Magpul PDR (5.56 PDW/Carbine) rather than a P90, the PDR did take some ergonomic aspects from the P90 so it does look alike, but more so like the PDR excepting that magazine placement.
Triangler bullet caeings were called Trounds.
And we're a concept for being able to hold more ammo. By interlocking the rounds.
I didn't even think about that aspect. The first thing my mind went to was the Puckle Gun. (Patented 1718 as "Puckle Machine Gun") It was designed in two variants. The first one used normal round bullets, nothing fancy. The second however was carnage as it used square bullets with square chambers. I figured the triangle bullets were a modern/futuristic reimagining of that concept.
(Unrelated but according to the patent the "humane" round bullets were for shooting Christians, while the square ones were to be used exclusively for Turks. That is literally what is written in the file)
The trianale bullets look like its just the belt thats shaped that way, too help the belt travel through the weapon easier allowing longer burts fire without the weapon freezing up, thats what i reckon anyway.
Paul knows his stuff. He is very informative. I look forward to seeing him on more videos.
Triangular because if square then you would need to space them out more, triangles allow the two rounds to be attached corner to corner but still let the belt bend in two directions. Square rounds attached corner to corner would bind up in one direction which would prevent them from being arranged in a box magazine, unless an additional linkage was added between each round. This will allow the belt to flex in both directions but would make the belt longer for same number of rounds.
Triangular shaped ammo could use a unique feed system, where a gear that has teeth the same size as the triangle between two rounds could feed rounds but any other shape is quite bad for that kind of mechanism.
Having any breach with corners is bad because corners are weak (also why gas cylinders are round etc). If you want to contain pressure then you can't have corners. Furthermore orientation of the round becomes an issue; a round cartridge will feed into the breach no matter how you rotate it, but a triangle can only feed in three specific orientations, even a slight bit of misalignment will cause a big problem.
Have them look at Depth. It’s got a good depiction of that underwater rifle that was briefly mentioned
I use the Koshka more over any of the other snipers so it’s noice that they find it’s design dope
Aside from SDM and the Vendetta, all snipers felt great to use and looked nice too.

I went to see these guys react to Infinite Warfare. BO4 was pretty grounded in reality but IW was full on outlandish, featuring stuff like an AK that shot plasma and a transforming shotgun/sniper rifle hybrid.
0:53 The Beretta 93r was never a full auto (machine)pistol. It had a very quick 3 round burst tho, something around 1100 round per minute. 🤩
Thanks for your comment and filling us in!
7:50 they came with 3 in fact, the APS, only underwater, the ASM-DT amphibian water but you need to change ammo, and th ADS, the amphibian assault rifle with amphibian ammo
The first quote of video is from Thunder Ranch. Oh yeah this is gonna be a good one
Thanks for your comment pointing that out! I had mentioned Clint Smith and Thunder Ranch while filming the video, but unfortunately it ended up on the editing room floor. Thanks again!
The outlaw is my favorite looking call of duty gun
The Titan looks like it’s made by Dardick and using Dardick Tround(Triangular Round)
Great video guys
The Titan use what looks like trounds, ammo that are embebed in a triagular plastic case. They problably got the idea from the Dardick revolver. a cool comcept of revolver that could be load with 20 rounds. It selled like ass, so they make a few thousand, but I think the comcept is still neat. They even had plans of multiple project rounds, before going bankrupt.
The triangular roinds might be for storage, maybe they roll together tighter so they fit more in?
more i need more from these 2 please !!!!!

....um....last time I checked pistols most definitely travel through the target or the body of a human being.
@@riotgear9116 Not really, it depends what kind of pistol. 9mm - 45ACP (the common pistol calibers) will penetrate through the body IF it's at close range.
@@fortuneherico2692 saying (not really) is like saying a butter knife wont cut your skin but if I forced the butter then it will cut. They still have the capacity to travel through.
@@riotgear9116 With the exceptions of it being point blank is why I said not really.
The rocket launcher looks a little bit like the rocket launcher from the film called Commando.
Triangular could be convenient for belt storage, or assist feed more than a round surface would. Really the only big justification for being locked into round shapes at this point is it's probably way easier to rifle, and when hand loading round is always "right side up".
But for a belt fed only system? No grunt fumbling more than any other belt fed. The HK was square but with a standard shaped boat tail, that seems even weirder than a triangular round with a triangular bullet assuming you can rifle a triangle. I think you can.
APS underwater rifle, it was in cod ghosts
Koshka seems based on the Dardick, which had a Magazine that fed to a revolver chamber. Now that I think about it, that makes sense for the thumbnail, too, because the dardick used triangular rounds called "trounds". Shout out to Forgotten Weapons channel for introducing me to that nuttiness.
The triangular rounds remind of the Dardick magazine fed revolver.
They were literally called trounds, as in triangular round.
It looks like the Ammo that the titan uses are sabot rounds with a sharp spike in them.
Could yo guys do a "Gun Expert REACTS to" the guns in the Metro games? that would be very interesting and cool. : )

I second this!

Triangular cartridges would stack perfectly inside of ammo boxes and not roll around like circular ones. It's a storage and manufacturing thing mainly.

Tfw the HK Slap is now a recommended action to perform, from HK themselves lmao.
It’d be cool if we saw the same guys react to MW2019’s weapons. :D
1:09 if I remember correctly, Caseless Ammo was a flop due to reliability issues, (I remember even less about that if it was the bullets & "casings" themselves? or the gun?) and because the casings doubled as heatsinks, and there'd be a risk that caseless Ammo could go off spontaneously.
OR did I read it wrong?
coming from the apex video, im really thinking about what military dudes would think of the apex tacticals and abilities. since, as the word itself is "tactical abilities"
riffle with revolver system does exist. So... koshka and especialy the outlaw are just waiting to be built.
the triangular casings seem to be an attempt to make them stack better inside a drum magazine.
whether it works in practice like that is yet to be seen, lol
It was actually a real design to try and make a handgun with more ammo capacity, it failed since the feed mechanism was really weird and no one really liked it. Also compromised the casings endurance by making weakspots on the triangle edges.
@@yeraymonzon6338 figured about as much
New favorite youtuber just because im a lefty shooter as well
0:56 this is from a free steam game called World of Guns: Gun disassembly. Basically a puzzle game where you find every little peace of a gun and take it apart. Then reassemble it in the correct order. There’s also different vision and slow speed modes so you can see the inner workings of the gun. They also have some vehicles and the 8& flak cannon. And a couple firing ranges for the ak and a few other guns. Reminder. The game is free for a duck ton of the guns. Go try it out. It takes less then a gig of space.
These guys explaining why suppressors should be made legal. Hearing safety
Seriously man, I wish I could afford one. NFA sucks
Triangle bullets would be pretty cool tho ngl.
Im pretty sure that most actual weapons can shoot under water... The worst problem is that they are join to jam eventually, due to the water oposing resistance to the movement of the mechanism. But... If you can operate It manually (like with any kind of Jam malfunction) you should be able to keep it shooting under water. This is because most bullets actually contains the requiered oxigen to shoot within the cartridge. This is because during the process itself its virtually imposible for the external air (with oxigen) to get inside the weapon untill the bullet has left the barrel or the mechanism has started cocling and the ejection port is at least partially opened. Though, bullets will be far less effective in water, due to they loosing energy quicker than when traveling through air.
But yeah... Russians made a "AK" (at least, influenced by AK's) to work under water, optimized to under water conditions. Work better than other AK's under water, but worse ouside water... So yeah... It existed, but i dont know if its really worth it.
