I just wanted to tell you , I really appreciate you taking the time to make these extremely informative videos, I don't ever remember another CZcams channel being so thorough..
I second that. It's very informative information all of us gun guys can use and appreciate plus as a NTMA graduate and former machinist, its entertaining as well. Thank you for your hard work. You do a phenomenal job!
I fear a ton of crappy ARs coming to market because of the recent panic buying. This is how the Chinese AR parts got into circulation during the last panic :(
Honestly, the AR market was the one thing that I didn't think I had to worry about where the parts were produced because you cant technically have foreign parts in a firearm that was made in the US. Not including materials or accessories, I didn't think I would have to look for a "Made in China" sticker on AR parts. Now that I know that is a thing to look out for I'll do my best to do so.
"I've explained it many many times" ~ Yep, just as I was about to ask the very question. So repeating it does help. I really appreciate the video's you make, I was a tooling inspector at McDonnell Douglas and love working with inspection gages and tools. I have just in the last few years gotten into the AR platform, was a .30 cal guy for 30+ years.
Just found your channel and I am really enjoying your work. I've always been interested in learning more about the inside of my weapons systems and their functions. Thanks for the dats
Chad you point out things like the rounded back edge of the BCG surface that engages the hammer. I wouldn’t have noticed that but understand why it is important. Thanks!
Happy Independence Day America. Thank you once again. I have been inspired to do similar inspections on my collection of firearms and building new firearms. I have purchased many additional tools recently, many of which have been featured here on your channel and also some from Marine Gun Builder. For more than 50 years I have been interested in firearms. Now retired, I have the time and assets to further pursue my interests. What better way to celebrate our country’s independence than by ensuring that we have the well maintained tools to protect and defend it.
I think I've watched 3 or 4 of your videos in the last day, and I've learned almost as much about the ar15 as I have in the last 3-4 years. Keep up the great work
When firearm quality is compared to automotive quality, the firearm industry is a hard failure. If 2% of automotive components failed in a similar manner, I would be instantly fired. If 0.2% of the automotive components were like this, there would be endless meetings and "help" given. The process controls in the firearms industry are garbage, although the military does have much better process controls and a TDP that are bot enforced. Civilian guns have garbage quality controls. I've had the experience of testing handguns and rifles for acceptance and legal purposes. The results are not pretty. The dishonesty in firearms marketing is creepy. Lies, lies, and more lies. Many "experts" are paid off or are useful idiots. It is refreshing to see people like Chad do the right thing. Facts do matter. The only saving grace for the civilian firearms industry is that 99% of all guns see less than 50 shots in their lifetime. I made up that statistic. An unused Taurus handgun will never fail. A safe queen AR will never fail, because it is never used. Imagine the warranty horror for a civilian AR company, if every owner fired a small amount like 1,000 rounds through their AR each year.
@@randymagnum143 I don't know what your specific issue is, but either they make terrible alternators or whoever is working on your car is laughing their way to the bank charging you for alternators over a short thats draining your battery
Believe what you say 100 percent. Guess there isn't really anyone to keep them accountable. Governments, mil, cops etc. Who buy big contracts probably don't even do testing this extensive and even if they do it's just their batch.
I know how my ar works... but watching you for 3 of these videos showed me what can go wrong and why. I had a limited understanding but I've learned a lot. The cam hole can stretch? I dont have the tools you have but at least I know what signs to look for and what it could be. I'm happy to know that my manufacturer has an excellent reputation for quality control but I'm gonna stay on top of things as best I can...at least now I have a better idea of what to look for
Very interesting. Do you have gauges to check large frame AR10 style rifles? Would be cool to see if some of the premium manufacturers are worth the coin. Thanks for putting out these informational videos.
Very happy to find this channel. Just recieved a complete upper from a dealer online out of Georgia and the bcg has some things that worry me. No MPI marks on bolt. Cam pin very loose in bolt as it almost undersized. Also I can't seem to find out exactly what spec bcg they use in there builds...lol. where is your shop based out of? Would love to send in a few things for inspectiong
I could have missed this in the video but I would like to know the round count of each one of these products you dissect Sir. Also, it would be cool to hear your overall opinion on these products or an Opinionated rating scale score. these are unique and informative thanks
That's because PSA at least at one point never made their own, usually they were made by Toolcraft inc. which is a very respected BCG OEM manufacturer.
@@VCBird6I remember seeing a video awhile back with the CEO and I know they bought some companies that made certain AR parts and I lot of new machinery. Yes they offer Toolcraft bcg's still and pretty sure they make their own now for most of their kits now. I once bought a deal with a Magpul D60 and a BCG for 129. I needed the BCG so I was like hell yeah buy a D60 get a BCG for free basically. I kept the bolt because it was ok MPI tested but the carrier was junk and threw it away. Don't know who made that but it was junk!
Where can we buy some of these gauges ? Pretty interested in the Bolt gauges. I'll keep checking the other videos to see if the info is there as well. Just figured it might be quicker to ask.
Thank you for the quick reply for information regarding the iGage gauge. So, since it is a fabricated part, and I like numbers reading, the no-go or go reading not good enough for me, precise reading better. I will see about having the one small piece fabricated for me by a local gunsmith, but one problem, measurements. So what is the dimension of that piece if you know or recall it and the part used for fabrication? Thank you!
Its true that only a handful of manufacturers are rebranded into hundreds of small brands. However I have an aero bolt, I definitely think its from a different manufacturer, it doesn't have any of the negative features of this Anderson like YFS fasteners, rough machining, sharp edges and the overall profile of the bolt is proprietary where the aeros are milspec.
The balance is, reportedly the training for cost you get while wearing out a barrel a little faster - just a little. I've seen the calculation, and considering how modular AR-15's are, it makes sense that the money one will save by shooting out a barrel with steel-case ammo will make up for buying a new barrel. This would seem especially true for a general-purpose AR with barrels that aren't $600 or more. Many shooters are quite happy with mere $120 barrels, so... hell, shoot them out (if you really can, and if you really have the time), then buy another barrel with the money saved.
Along time ago when steel cased was coming into the country by the boatload, I would shoot thousands of rounds of it. Just about everything I could get. .45 acp, 9mm, .223 and 7.62x39. I was curious if I could reload it. I figured what the heck. The primer was a little difficult to get out because it was swaged in place BUT the steel case was just as soft as brass for as far as I could tell. In the reloading process, I would treat the case the same way that I treated brass and couldn't feel a difference in resizing or any of the other steps involved. I don't know if that's the CASE (see what I did there?) now but they were fine back then. It was the late 90s, so things may have changed.
@@samcoon6699 there’s a video on CZcams where a man does several Rockwell test on different steel case and brass cased ammunition. The results of this show that there is very little difference between the brass case and steel case. The steel they use is very soft.
Been watching for awhile first time commenting love all your manufacturing level equipment you have to work with. but I did have 1 question at the beginning of the video when you compared firing pins the inadequate protrusion was attributed a defective firing pin but later in the video when you measured the cam pin hole in the bolt from my point of view it showed bolt stretch. in your opinion could that account for the protrusion issue. Just trying to understand if firing pin was actually out of spec as well as the bolt. Great video as always very informative
The pin may have cleared minimum spec when the bolt was new and now that the bolts stretched it fails. Would have been interesting if he checked the firing pin in a different bolt
Would be interested to see how many flaws you can find in my DD with a thorough inspection like this.. Something to start with the bolt catch can't properly reach the follower of multiple different magazines so it jumps over it and shears the edge of the follower off.. Resulting in the bolt not locking back on an empty magazine and sometimes getting the magazine stuck when the bolt catch jumps over the follower.
I have a question based on the review of YFS fasteners. I have a brandnew AR in which the gas key is equipped with a YFS fastener. Single screw because it’s a SFAR (SHORT FRAMED AUTO LOADING RIFLE and it is chambered for 7.62x51 NATO /.308 WIN. The YFS screw is staked both sides but I know they are notorious for failure. Should I swap it now and save the heartache or wait?
Because im poor i wonder if my budget ar 15s could benifit from lapping compound on rough surfaces in the three bore area if one was careful and had the proper bore scope to find rough spots ...
Looking forward to you doing a physical on a giessele carrier. They're supposed to have a really good finish inside due to the special machine they have to do this.
I wonder if Anderson is using the sharp shoulder om the bolt-to-hammer interface to delay the bolt unlock fractionally, in the same manner that on a 1911 in .45 Super the square bottom on the firing pin retainer plate delays the unlocking on a 1911? If not that, it might just be sloppy machining on the carrier.
Question: When replacing the bolt carrier for a completely new one is there anything we should worry about, is it plug and play? Been looking at a Radion BCG I'm not sure.... Thanks!
I just found this channel. I'm amazed of your knowledge sir, appreciate all your videos. How much does it cost for you to check AR's out?. Also what bcg would you recommend may i ask?. I've got all colt bcg's but im aware of no company is 100% in mfg they're wares. Thanks again bud! 👊
So, new firing pin, new ejector spring, barrel is clocked in the upper receiver, bolt tail may be undersized, new extractor spring, camp pin hole is elongating so whole bolt is toast, magnetized parts, gas key is a bit oversized, gas key screws were loose so needs a new gas key and screws, and the whole carrier is a bit rough inside. My first priority would be to fix the upper, so that when you replace the bolt it's not getting beat up. If I have the cash, I would do both at the same time.
Good info I've been using the donuts and never had extractor problems before using them.and I had a recoil buffer break in a 1911 ,which prevented the slide from fully retracting. Fine for the range ,but for defense ,you have to rethink it .
I heard YSF fastners were stronger than MOAKS in one test by a youtuber. His theory was staking one side at a time side-loaded the screw head weakening the screw.
Aircraft maintenance school we're taught to unload our torque wrench. They also get sent to get calibrated once a year. If you leave it wound up, you have to send it to be calibrated
I have to agree, ALL torque wrenches need to be turned down, I have the Fat wrench and also a extremely expensive Snapon 1/2 inch wrench and would never put it away without zeroing the setting. Think of it like a stiff pistol recoil spring, don't we put it away slide back to lesson the springs strength. Plus it takes a second to do, why not error on the side of tool..
@@totenkopfelite88 springs do not lose their function through being compressed, but rather from being expanded and compressed repeatedly. You can leave magazines loaded for 60 years and they won't have issues feeding.
@@ihadalife1177 I just watched his part 1 and part 2 of a LMT Enhanced. I'm knew to all of this, but I think that specific BCG had multiple Machining Issues.
Man I like Anderson I would like to like them more but when their stuff is tested it is usually crap.... 😢 I have some uppers and lowers from them but have never dared to buy their barrels or bcgs.. gas block is as lowbas i will go.. it's to bad because its like buying a American made car. Compared to buying a Toyota... We want to buy American but we have to buy Toyota for real quality.
23:20 Agreed 100%, as of now, it's plenty enough of Karens out there :] I am not American, but - Happy 4th of July! Love your channel - attention to detail, failure points - knowledge & experience in general. I learned many things watching, and for that - thank you!
HI ! I have an AR15 that I broke the front sight , gas block off. It's an A2 style just the base is left , Can I replace it with another A2 type sight ? I have one thats used , and alredy drilled ,it was police surplus that they took off new rifles to put on low profile ones . I really want that type sight , Thanks
A2 style gas blocks are pinned on in two places, if you have the right tools you can do it yourself. Just make sure you hit the taper pins out the correct way or else its gonna be a real good time.
The taper pins on a FSB are custom for to the barrel. The odds of putting a pinned FSB on a different barrel are low. There are ways to put a new taper pinned FSB on a barrel, but very few AR gunsmiths have the tools to do that. It is beyond what someone can do at home. It may be cheaper to buy a new barrel with thr FSB i stalled. How did the front sight break? The FSB is some pretty tough steel. How can you be sure that the barrel did not bend when the damage to the FSB happened?
Hey I got a bca bgc laying aroind if you want to do a video on it. Maybe 300ish rounds through it. I don't use it anymore but if you're interested lmk!!
@@hairydogstail I have six BCM rifles with tens of thousands of rounds through them and not a single failure of any part. People scream its just a roll mark yet the QC between BCM and anderson is not even close. BCM all the way.
@@SchooloftheAmericanRifle ar15 is really a/an excellent firearm, but ak's aren't as finicky. Not trying to be a smarty, but I like both guns and to be honest the ak is more robust. I know ar 's are way, way more accurate, but sometimes you have to give a little to get a lot back. Still like your video.
I don’t know what you’re trying to say? AKs need to headspace just like everything else. Their firing pin has to function the same as everything else. A good AR will run with a good AK and a crap AR will fail right next to a crap AK.
That is the first time I've seen anyone go through all of that stuff. Very interesting. I carried an M16 in the Marines, have had multiple ARs over the years, have built several of them and done numerous lowers and have never seen so much cool stuff all in one video! Very well done!

Agreed. As a farm kid that hunted with bolt guns I found the M16's in Nam to be suspicious of.

Technically shouldn't this video be named "autopsy" due to the gas key screws failing the reverse torque test? Among the several other smaller issues.
I just found this channel. I'm amazed of your knowledge sir, appreciate all your videos. How much does it cost for you to check AR's out?. Also what bcg would you recommend may i ask?. I've got all colt bcg's but im aware of no company is 100% in mfg they're wares. Thanks again bud! 👊
Firework got ya heh? Lol. Great stuff thanks sir.
Sorry, I jumped! 😂
@@onna-day7047 : Me too!
Can the chrome lining in the carrier be polished to improve the surface?
If it's so important that the gas key and carrier stay together, why don't we just make those in one component?
So, new firing pin, new ejector spring, barrel is clocked in the upper receiver, bolt tail may be undersized, new extractor spring, camp pin hole is elongating so whole bolt is toast, magnetized parts, gas key is a bit oversized, gas key screws were loose so needs a new gas key and screws, and the whole carrier is a bit rough inside.
My first priority would be to fix the upper, so that when you replace the bolt it's not getting beat up. If I have the cash, I would do both at the same time.
Chad, I'm sure you've mentioned this in other videos, but why do you not like to see both the o-ring and the extractor insert?
Iirc it runs the risk of excessive extractor strength
At least from what I have heard, it also is not very reliable over time as the rubber deteriorates.
Good info I've been using the donuts and never had extractor problems before using them.and I had a recoil buffer break in a 1911 ,which prevented the slide from fully retracting. Fine for the range ,but for defense ,you have to rethink it .
@@davidschaadt5929 no machine is 100% infallible .
looks like a stress crack over the cam pin hole
How many rounds has it fired? And was it still magnetized from the MPI process ?
I heard YSF fastners were stronger than MOAKS in one test by a youtuber.
His theory was staking one side at a time side-loaded the screw head weakening the screw.
Fat wrench and every Snap-On both recommend winding down their wrenches.
all torque driven tools or spring loaded tools need to be wound down or turned off before storage.
Aircraft maintenance school we're taught to unload our torque wrench. They also get sent to get calibrated once a year. If you leave it wound up, you have to send it to be calibrated
I have to agree, ALL torque wrenches need to be turned down, I have the Fat wrench and also a extremely expensive Snapon 1/2 inch wrench and would never put it away without zeroing the setting.
Think of it like a stiff pistol recoil spring, don't we put it away slide back to lesson the springs strength.
Plus it takes a second to do, why not error on the side of tool..
@@totenkopfelite88 springs do not lose their function through being compressed, but rather from being expanded and compressed repeatedly. You can leave magazines loaded for 60 years and they won't have issues feeding.
@@hellcatdave1 wrong
I have a aero precision bolt that I would like to get tested
@@petersouthernboy6327 nothing wrong with aero
😆 “I’m not a Karen.”
Today I learned that the gas seal on my bolt might be bad.
HOW MUCH FOR A CARRIER AND BOLT ACCESSMENT DO YOU CHARGE?IF I HAD THE TOOLS ID DO IT MYSELF, MAN YOU HAVE NICE TOOLS AND ARE A GREAT TEACHER!!!!
HES the rifle version of the guys that do really good car videos !!
Who do you think makes the best BCG's ???
LMT?
Toolcraft?
JP?
How would you rank your top 3 BCGs ???
Only thing he's said about bcgs is that he hasn't seen an LMT enhanced, Knights e3 or JP bcg break ever.
@@ihadalife1177 I just watched his part 1 and part 2 of a LMT Enhanced. I'm knew to all of this, but I think that specific BCG had multiple Machining Issues.
Sionics
Forward Controls Design
Colt
SOLGW
These seem to consistently do well
toolcraft makes a good bcg. put many rounds through many with no problems .
@@MrKadidle51 no way SOLGW makes their own bcgs.
I would also like to know how much for a bcg autopsy please?
Thanks
Man I like Anderson I would like to like them more but when their stuff is tested it is usually crap.... 😢 I have some uppers and lowers from them but have never dared to buy their barrels or bcgs.. gas block is as lowbas i will go.. it's to bad because its like buying a American made car. Compared to buying a Toyota... We want to buy American but we have to buy Toyota for real quality.
This was at 300 rounds?
Anderson is junk so....
@@zack9912000 its not junk, junk still has a use. Anderson doesn't have a use
23:20 Agreed 100%, as of now, it's plenty enough of Karens out there :] I am not American, but - Happy 4th of July!
Love your channel - attention to detail, failure points - knowledge & experience in general. I learned many things watching, and for that - thank you!
Hey Chad, can I send you an out of spec BCM barrel nut?
What causes bolt parts to magnetize?
Magnetic Particle Inspection usually.
@@SW990 more specifically, not demagnetizing them after MPI.
Machining steels can cause magnetism.
Bolt tail and bolt ware is definitely from the owner cleaning with wire brush. Fudd stuff
HI ! I have an AR15 that I broke the front sight , gas block off. It's an A2 style just the base is left , Can I replace it with another A2 type sight ? I have one thats used , and alredy drilled ,it was police surplus that they took off new rifles to put on low profile ones . I really want that type sight , Thanks
A2 style gas blocks are pinned on in two places, if you have the right tools you can do it yourself. Just make sure you hit the taper pins out the correct way or else its gonna be a real good time.
The taper pins on a FSB are custom for to the barrel. The odds of putting a pinned FSB on a different barrel are low. There are ways to put a new taper pinned FSB on a barrel, but very few AR gunsmiths have the tools to do that. It is beyond what someone can do at home.
It may be cheaper to buy a new barrel with thr FSB i stalled.
How did the front sight break?
The FSB is some pretty tough steel. How can you be sure that the barrel did not bend when the damage to the FSB happened?
Hey I got a bca bgc laying aroind if you want to do a video on it. Maybe 300ish rounds through it. I don't use it anymore but if you're interested lmk!!
Forward assist cuts look angled.
You can demagnetize tools with a magnet and a drill.
EDIT: of course you already have a demagnetizer 😅
And that is why you buy a BCM
Plenty of bcm fails on this channel. Bcm doesn't even make bcgs iirc they use toolcraft.
@@hairydogstail I have six BCM rifles with tens of thousands of rounds through them and not a single failure of any part. People scream its just a roll mark yet the QC between BCM and anderson is not even close. BCM all the way.
You have just convinced me in why an AK is better. Russians don't care about aircraft specs on a gun. No offense , truly. Good vid, man !
I have gauges for AK's too. Soviet and U.S. Made.
@@SchooloftheAmericanRifle ar15 is really a/an excellent firearm, but ak's aren't as finicky. Not trying to be a smarty, but I like both guns and to be honest the ak is more robust. I know ar 's are way, way more accurate, but sometimes you have to give a little to get a lot back. Still like your video.
I don’t know what you’re trying to say? AKs need to headspace just like everything else. Their firing pin has to function the same as everything else. A good AR will run with a good AK and a crap AR will fail right next to a crap AK.
Got the first view!!!
