Smyth Busters: Do You Have To Clean a New Barrel?

- "If it's brand-new, why would it need to be cleaned? You don't have to clean a new barrel." That's the advice some Internet sages have been throwing around. But we know the value of a lot of the info on the Internet! Is this good advice? NO, say Brownells Gun Techs™ Steve and Caleb, and they've got out the borescope to show us why. An internal tour of a factory-new AR-15 barrel reveals a coating of grease in the bore and, more importantly, in the chamber. If the grease is thick enough, it'll prevent the case from extracting after firing, leading to a jammed gun. The grease can also constrict the chamber, causing excess pressure leading to excess bolt velocity, which results in a malfunction, too. Worst-case scenario, the grease obstructs the bullet's travel through the bore and causes to a blown-up gun, the dreaded and very dangerous KA-BOOM!
So this myth is handily BUSTED. You do have to clean a new barrel, whether it's a replacement / upgrade or part of an entirely new gun. Run a cleaning patch soaked in solvent down the bore. You don't need to get out the copper solvent or scrub until your arm aches. You just want to remove any grease that was put in the bore and chamber to protect them during shipping / storage. That simple cleaning is the best way to be sure there is nothing in the bore that shouldn't be when you fire that first round.

I have always cleaned and lubricated a new or used firearm. This adds to the fun and enjoyment of my puchase. It's also fun just to see how each manufacturer's design works! Good stuff guys!
yepper
As a rule of thumb...barrel or gun it doesn't matter I give it a quick clean no matter what. Remember Murphy's Law.
Caleb out here gettin' WILD!
9.5 on the syncro sip. Nailed it. Not only barrels, but the action too. I have found an amazing amount of leftover metal chips and even small tabs not completely removed after machining. If it is an old milsurp, it is a must to clear old cosmoline. Don't forget a dry patch down the barrel of a stored firearm before firing, just to make sure no oil seeped in.
The banter between you two in the intro is fantastic. Don't get rid of it.
Yes, for safety reasons I ALWAYS inspect the barrel of ANY firearm for blockages, and run a lightly oiled patch.
I always field strip and clean a new firearm or barrel, I actually got metal shavings from a firearm before, and it was a good quality brand!
Two new Aero Precision barrels I received last year both had packing grease and metal shavings(!), presumably from drilling the gas port. The wizards that work in their tech dept advised to shoot it to clear out the metal. Fantastic.
Story time: Bought a brand new barrel from FN had it installed had no idea it had packing storage grease inside of barrel was only able to crank off a few rounds before gumming up!
Took it home properly cleaned it and runs like a champ!
Live and learn!
Not for a colonoscopy! That was hilarious!😂
When I get a new firearm, I run some patches through the bore with #9. Then brush it out with 10 strokes using a brass brush. I leave it overnight and then use Gunscrubber to blast the crud out of it. There is generally a LOT of crud that comes out. I then patch with #9 until it comes out clean.
Good humor - I enjoyed watching Steve’s face when Caleb said he could no longer do the colonoscopies for him
Great content guys! God bless, stay safe!
I run a patch or two then a boresnake. That takes care of anything that may have been left behind in the manufacturing process.Better safe than sorry.
Totally agree with the content of this video. Especially for new gun owners, it's not only a good idea to properly inspect/clean a new firearm, but it's a great opportunity to learn about its functionality, get familiar with operation of it. Educate yourself of basic mechanics of how everything works, dry-fire it (unless it's rimfire), etc. Being familiar with how a new gun should look, function, and feel helps with identifying a potential malfunction down the road.
Enjoy every episode of SB! Thanks guys! :)
Life pro tip: clean anything that came out of a machine shop before first use.
Brownells Smith Busters with Caleb the most dapper.
Hell yeah, I watched the awards too. Most Dapper.
Thanks Steve and Caleb. Good info from pros. Preaching to the choir for many of us, some out here needed to hear this. Run a dry, clean patch thru the bore, or pull a caliber specific bore snake thru it, before firing live ammo. Never hurts to check the bore, before loading. If it’s been out of your sight, control or presence, you don’t KNOW it’s clear, unobstructed.
I remember cleaning a brand new CVA 54 cal in line grey laminate stainless version the first year they came out. Was around 91’. The rifling cuts were all left in the barrel after machining. That POS would never hit the broad side of a barn. The stock cracked on it after a few shots as well. Bought a night BK92 after it was returned.
😅😅 I am still laughing from that opening line! Is that wind burn on your face Steve or just blushing from shock!😅
Omg the bore-scope humor at the beginning....and it says not for medical use...sorry Steve 😅😅😅😆🤣
I always clean the chamber out before a headspace check anyway so might as well clean the rest of it. Certainly won't hurt anything.
The last two rifles I bought had dirty bores. I always give it at least a once over with bore solvent. My first rifle was an AB3, and the manual said to clean it before shooting.
I was surprised that you did not talk about the use of J_B Bore Bright &Bore Finishing compounds. This would be the best time to use these products prior to mounting the AR barrel to the receiver. Note that you will need to clean out the gas port when you finished.
When I got my Mossburg 590A1, I was loading and unloading dummy rounds to insure the spring, follower, etc. were in good order. Loading shells felt gritty, so I disassembled and ran a mop through the magazine tube, found several pieces of what I thought was unburned powder. Lightly oiled with a patch, reassembled the spring/follower (actually swapped out the OEM follower for a GG&G) and it was fine.
The banter between you guys always kills me
Congratulations Caleb on the Gundies Award, your hair looked fantastic at the show!
Thank you!
So, add running the chamber brush to the new barrel brush op. Got it. (ARs especially)
Another great video.....the one thing I would recommend is being sure that the barrel has a good coat of oil.
Cleaning is a must to me. Not a hard-core douche but least a break down an light clean. Familiarize yourself with the platform n how it may run or see any issues. For example I bought a new ar recently, great gun but somehow overlooked a big bur in the ramps n was causing sever scraping of the round n accuracy issues when feeding. Slowly polished it out and she's mint!
Yes Indeed, always give a new barrel a light cleaning.
I always strip and clean every new firearm I get. To make sure there are no obstruction, there is no grease where there shouldn’t be, oil where there should be, and nothing is broken or out of place.
I've always used aerosol spray gun scrubber and a patch or two down the barrel before shooting a gun just to be safe and make sure there's nothing down the bore that may scratch the rifling run the patches through and flush the barrel with the spray just for the heck of it to get out anything the patch may have left behind
On a new barrel to you, new or used. Hoppe's #9 first, plastic bristle brush second, dry patches till clean third and a very lightly oiled patch fourth. Then, one is good to go for shooting or storage.
Definitely run a patch through it at least. I had to mortar a bran new rifle bc of oil in the chamber.
I believe it's mandatory to clean a new barrel, nomatter the platform. I've pulled metal shavings and weird looking gunk out of brand new, never fired barrels. I don't go crazy or anything... A simple bore snake pull then some good ol mil-comm solvent on a patch followed by a nylon brush back and forth a few times, let her sit for 5 minutes and then dry patches till you don't see anything. That's when it's time to use mil-comm grease! Not only is the grease the absolute best corrosion protection, it will stay put for however long it be necessary. When it comes time to shoot for the first time the grease now helps aid in breaking in the barrel since all the microscopic imperfections have already been filled.
Damn barrel bugs….. Thanks guys
I strip and clean every new / used fierarm regardless of how clean it looks before I ever shoot it. It's important to inspect every fierarm. it's a safty thing
Got a new ROSCO barrel delivered today. I’ll be cleaning it before it’s installed.
Last two barrels I bought had so much thick grease that I had to run double the amount of cleaning patches through it compared to a range day. Maybe an alcohol soaked patch would have worked faster but what cleaning lubricants I was using couldn’t cut the thick grease.
Wd40 works well to denature grease
I'm one to always inspect, clean, and lube a new gun, but now you got me all paranoid about the DD M4A1 I bought from yall not too long ago I have yet to get out to range since building up a full rifle. Time to do a quick swiping of that barrel.
I bought a new budget AR one time. Hand to god there were metal filings in the upper around the barrel extension. I cleaned the hell out of that thing.
Wow, Steve went full on BLUSHING real fast today!... I wonder why? 😉
I always clean before first time out. It give me a chance to do a basic fit and function check as well as clear out any excess grease or oil.
If the first firing is on an odd numbered date it is best to first rotate counter-clockwise as viewed from the butt end along the vertical axis at least three times but no more than eight full revolutions. If an even day clockwise. This will ensure maximum accuracy by polarly aligning any errant neutrons with the angular momentum of the Julian offset correction quotient.
I have cleaned every New AR barrel, I have bought. 100 % of them were dirty. Some, had what looked like, minor rust, inside the barrel, where they'd sat in a warehouse for god only knows, how long!? But when done they are clean, and lubed, and ready for use.
I run a dry path through the barrel, then eyeball the bore under a light. If it is greasy I use solvent followed by a dry patch.
Clean your barrel and clean your whole firearm when you buy it check it out most firearms are made as quickly as they can get them out the door.
Nearly every firearm I've acquired has, if new, some kind of anti-corrosion compound on it and in it, even stainless, as it's rust resistant not rust proof. If used, you have to assume that the previous was not meticulous in cleaning. Military surplus stuff has shown up with the standard cosmoline dip tank application, so yeah, cleaning is essential. It's also informational in the operation aspect of said firearm.
Always ALWAYS clean it.
Buy it in a store or have it shipped in, who knows what could be in there.
If I haven’t shot one of my own guns in months, I run a patch or two, simply to be sure nothing crawled in there & to asses it’s condition.
Congratulations on the Gundies. Stay sharp.
I've bought many, many new guns and every one of them had been test fired and not cleaned. Must every one also had a rust preventative/grease/oil applied to it. I clean and lube them properly prior to firing them. I go 1 step farther and season each barrel of new gun I buy. It provides better accuracy and makes it easier to clean them in the future
I like running a patch with simple green then normal cleaning on a new me firearm. Unless I see cosmoline. Then I fully strip it, take it out to my truck and put it on newspapers and let the sun bake it. Amazing how much of it runs out everywhere!
Excellent video! Very useful info.
Always inspect anything new very thoroughly.
I appreciate these segments!
It definitely seems obvious now, but I was never told to do this growing up, by anyone, ever. My father, grandfather, brother, no one ever told me to clean a new gun before I fired it. I never read it anywhere either. Furthermore, not once when I bought any of my guns did any of clerks helping me with the sale suggest I clean before I fire. Even in high school, I worked at sporting goods store that sold guns. I worked the gun counter for a year, and again, no one ever suggested this to me.
Last year I bought a new Daniel Defense M4A1 and took it straight to the range. After seeing videos like this and thinking I did damage to the barrel, I actually called DD and told them what I did. The sales rep at Daniel Defense laughed and said it was no issue at all. It's a cold forged barrel and not running a patch through it before I fired it would cause zero damage. I also looked in the manual, and it doesn't say anything about cleaning before firing.
All that being said, going forward any new gun I purchase, I will clean before I fire. But I don't think taking a gun straight to the range will cause permanent damage to the barrel like some suggest.
Daniel Defense makes cold hammer-forged barrels. That means the rifling is not cut into the barrel it is hammered Into it. If you have one that has cut rifling, which is most barrels then there could potentially be some metal shavings from the manufacturing process. There can also be some metal shavings from threading the barrel.
If you never run a cleaning tool through a new barrel, it will most likely not cause massive or noticable damage. It could cause some damage that is so minor that you cannot see it without some kind of special equipment like a microscope or something. It only takes a few seconds to push a patched through a new barrel and is just a good idea to do, even though it's most likely not going to ruin the barrel if you don't. In most cases I don't think a thorough cleaning is needed, just push a patch or mop through it once.
Daniel Defense is a very premium company and they probably run something through the barrel at the end of manufacturing just to make sure it is completely ready to shoot. I have one of their barrels and it is excellent. I did run a slightly damp patch through it after assembly.
yeah I have found that cheep as well as expensive barrels have something in then maybye just resadue but in some ar-15 barrels ive seen snall metal chips. Probaly just the gas port hole but either way, I always clean before the first shots.
I clp, then 1-2 brush runs, bore snake, then finalize with a patch with rem oil on it.
There is no reason you shouldn't go through and clean a new gun when you buy it. Just do it!
100%
Just got a new barrel scoped it before the first patch found all kinds of crap in there and a spotty parkerized finished that I hope will not cause abnormal wear. I inspect and clean every gun and every barrel before ever puting rounds through. Your life may depend on it.
I find lighting a bunch of dried sage and waving it in a figure 8 over the barrel is a good way to drive out any evil spirits that might cause malfunctions. 🤔
After appeasing the machine spirit one should also remember to chant the litany of maintenance and give thanks to the Omnissiah.
I always clean a new barrel with a wipe using Hoppes then a dry patch or 2. My first shots are always to sight in iron sights or a scope so why waste ammo when gunk in a barrel may impact point of aim?
It's hard to accurately check the headspace with a chamber that is not clean.
I've experienced this. Cleaning the barrel resolved the problem.
I believe that cleaning makes it truly yours you familiarize yourself with it nice video
Teardown inspect clean relube and reassemble.
Definitely clean a new barrel, just got a 223 Wylde barrel that had been nitrited, I got a lot of black residue out of it! Also had to remove a small piece of aluminum that was stuck in the charging handle raceway of the upper receiver. I always inspect any firearm new to me before firing.
Heavy CLP patch, let sit a bit, brass brush, dry patch till clean, then light CLP.
😅😆😅
Good info.
Yeah agree, I always run a few patches down a new barrel. There's old cutting oil, grease, and micro metal chips leftover from the manufacturing process.
Always take apart, inspect and then clean and lube a new firearm ! Barrel and action. You'd be surprised at the Gunk and crap I've come across! I personally enjoy cleaning firearms never thought of it as much of a hassle!
I bought a Ruger AR-556 and tge damn thing would not run when I bought it. Got pissed off thinking it was a lemon at first but this is all it was. Cleaned the barrel and never had an issue with it as long as I had it.
Hmm, I've never done this. Never thought about it. I will from now on.
I got my start shooting with milsurps 50 years ago...they were always loaded with grease and cosmoline, inside and out. It has never occurred to me NOT to clean a new gun or barrel. There are gun reviewers out there that don't clean or lube a new gun being tested, and I just do not get it.
I always swab a barrel because you never know if* a metal shaving was left behind from the manufacture. And if a round goes down the bore with a small steel shard in the way, it can permanently damage the barrels accuracy.
It takes no effort to clean a barrel so just do it.
I always run a patch or two dry, then MAYBE one or two with light oil
I always clean and lube any new gun... Even new stuff can have issues, and a good 'field strip and cleaning' is a great way to inspect
Nobody even cleans a new gun before they shoot it! Thats the first thing i do! Its unreal. Then they wonder why it wont work right. The stuff i have seen come out of a new gun is impressive. Metal chips from machining and abrasives, yuck.
Sniff Busters: Caleb gives Steve a colonoscopy
Seems like common sense to give you gun a quick clean before shooting it. Never thought this was controversial or “bust worthy”.
I’m guilty for not doing that. When I was younger and couldn’t shoot on my own property, I would clean and baby the firearm all the time but now it seems I just grab the new toy and run it immediately then clean it. Maybe I’ll slide a patch down the hole next time.
Anytime I buy a new firearm I check it all out, clean and lube it. You’ll be amazed at the crap that’s down inside
I didn't know that. Cool thanks
I've always understood that it's Cosmoline, but yes! - Clean your new barrel.
Every time I bought a gun it hade factory Ole in it, I actually take it apart then clean it then I know for sure it's good and clean.
Thoughts on cleaning new barrels after the first few shots. I have one rifle that says used patches after each of the first 10 shots. Then at other Intervals afterwards . But another one doesn’t mention it.
From time to time I see multiple "reviewers" shoot magazine after magazine in a brand new firearm as they try to convey their brutal honesty that "this is how they make it and it should be ready to go" mentality. What a perfect way to screw up a perfectly good gun! I clean and oil ALL my guns...and PARTICULARLY when they are new.
Interesting...the upper receiver I got for the last AR build had something that looked like rust in it. It was more than just in the chamber or in a few places. It was pretty much all through the barrel. Wonder if that was grease as well???
Thanks!
This is one of those things that I know I should do but often fail.
Ya cleaning a new barrel makes a lot of sense….. who knows what the factory could have accidentally left behind
I usually always clean a firearm when I get one new or not, but what I do not understand do you need to break in a (new MSR barrel)???? Barrels such as AR-15/10/9 AK-47/74 etc.???
Definitely inspect and swab. Every one. Just not worth not knowing and having a bad time
Every new firearm related purchase I make gets broken down, inspected, cleaned and lubed. No exceptions. Shipping goop, foreign objects and manufacturing crud exists.
I always clean a new to me firearm, including the barrel.
This episode was "super easy", just like Steve's coffee mug!
"Super easy, Barely an inconvenience. "
Love the pitch meeting videos.
Wonder if Ol` Pete Bootyjuice knows about a bore scope? Might help him find that missin` Gerbil. [ Always clean a new barrel ]
It can't hurt to clean a new barrel, but it can hurt to not clean it.
I`ve always been taught to service a new firearm because of the shipping and manufacturing lubes.
How do I know what may be in there that could mess things up. I have pushed patches down a new barrel and had small flecks of metal come out on that patch. Now that I have a bore scope, I am looking at the barrel before I run a patch down it.
