Years ago I was an armorer in the Army... if the Army had taken the time to teach me this 15 minutes worth of information it would have been invaluable to the unit. As is I'm glad I know it now, better late than never. Thanks for the incredible video. Never subscribed faster.

I was a company armorer also. It was not my main MOS. late 80s early 90s. I learned then they only want you to know the basics. I took it upon myself to learn. I was an E-4 at the time & they sent me to HQ arms room to help an E6 get his room in order. I spent a lot of free time disassembling, assembling weapons well above my grade. I also learned to get extra parts to have on hand. Just hide them during inspections. I also acquired parts that were not within my level (gas rings, extractors, springs, roll pins, etc). Better to have & not need than to need & not have. It always seemed to ring true in the field (live fire). I also used to take my tank apart to get ready for inspections. It was easier to repaint parts & get into the tight areas. Kept the tank looking new. We had the 1911 for personal weapon. Not much would go wrong with them. For we didn't really fire them often. Just something to lug around & get dirty. I never did get the Beretta besides being the first unit to use them in boot camp. This guy would have made a excellent armorer. Thorough & starts at the basics. The Army used to offer a course for gunsmiths. Credited on your personal time. It was mostly different types of military weapon systems (machineguns).

@@m1a1abrams93 sounds like the headaches are a constant throughout the generations. The Beretta was great. Got a good bit of time in with that one. I was running the ledger when we got the new M17s in. I never got to fire one, but I did like that you could swap out the polymer frame/body or whatever it's called, but I liked the ergonomics and features of the m9 better. My Walther PPQ is another story though. Took my shooting up a notch.

The community college idea is a great recommendation. My dad taught machine shop at our local community college for over a decade. They would probably do it for free just for the experience. I know in the class where my dad taught, there was a glass display cabinet where students would place items that they had machined themselves as a sort of testament to what things could be done by trained machinist in the beginning stage. It really helped to inspire new students. They could ask you if they could keep the other half of the cut out for the same reason.

As a Mechanical Quality Inspector I really love the 100% inspection that you do to find the problems. I'm impressed with the gauging you use and your understanding of why they are necessary. In a production setting I'll perform inspections per the the Print and customers requirements. Often times I won't know the "why" of certain dimensions.

Received a lot of new "AR15's" from a quality mfr. years ago for my Sheriff's Dept. On first day of issue & initial inspection & firing of the newly issued carbines, six were having function problems. No one was able to determine what the issue was. As a Colt trained Armorer for the AR15/M16 line of weapons, I had a hunch but was not there to witness the issues. I took the six carbines to our shop & found them all to have the hammer spring installed backwards from original assembly; exactly as I suspected. They worked flawlessly after proper installation. No other flaws were observed. I wrote up a report as to findings & notified the Mfr. They were very apologetic and based on the serial numbers were able to determine what staff person did the assemblies. Apparently that same person had similar issues in his past and was relieved of his employ there. Thankfully the issues were minor with no damage or injury resulting.

It seems like everything on that bolt was made large on the ID and small on the OD to account for plating. I see other machinists do this all the time thinking that they need to make everything at or below LMC to account for plating thickness, not aware that most plating is less than a thou thick. So they will make a hole .003 oversize to account for plating that is only say .0004 thick and their hole will still be too large. I see it at almost every shop I work at and if they don't have a good inspection department, a lot of it makes it out to the customer. This is made even worse when the engineer has already accounted for plating and it's factored into the tolerance on the print but the machinist doesn't know that.

Thanks for this video! I had an issue with a BCG that would fail to strip a round from the magazine. The machined grooves which ride over the top of the mag lips were too shallow (by about 20 thou IIRC). I didn't have your suite of tools on hand, but I did at least have a decent set of calipers which gave me a good-enough measurement of this particular manufacturing defect. Fortunately the mfr. stood by their product and replaced the part with no questions asked.

I’ve noticed that some ar bcg’s let off so much gas that you cannot comfortably shoot next to one at the range (guns without a muzzle brake), also wearing covered ear protection with your mouth open blows air out of your nose, it’s a strange sensation to describe. I’ve seen one where the adjustable gas block is open all the way for the gun to cycle properly. I know this video is two years old at the time of this comment, but this is a great video and I assume that I’m describing how this bcg would likely operate. Would these bolt conditions lead to poor accuracy?

But, but, but...loose tolerances let rocks and dirt work themselves free of the bolt dood! That's why AKs NEVER fail - you can pour communist rocks through the ejection port using a Warsaw shovel and they'll simply get blown back out! Oh-ho-ho! That's been said many times, but one of the good things about our modern area and the internet is that it allows the average person to test things these for themselves and post proof of their results. So there are several videos out there of people shoveling muck atop AK-patterns and AR-patterns and comparing their performance...and many would be surprised to learn all but the most cruddy AR will run in the face of what causes AKs made of some of the most legendary, most authentic, most Russian parts kits seize up. Disclaimer: Of course, there are exceptions between certain individual guns/builds, different tests, etc - but overall? Yeah - much easier to lock up an AK short term than an AR. Disclaimer2: In the AK's defense, it does indeed seem easier to get running again after nearly melting the barrel and then banging that drooping barrel with a hammer until it is straight and having your friend's T80 tank run over the bolt to get it to fit again, or digging one up after it's been in the dirt for 40 years and throwing it against a hill to chip off the rust...but - in all but the most extreme circumstances with the most extreme lack of spare parts and gunsmiths and lubrication and literally decades of neglect...AR > AK.

Tbh an AK runs better when tolerances are met too. It's just that the design allows for more slop without affecting function.

Any manufacturer is going to have out of spec components. Some would recalibrate and toss the rejects. These days, particularly in some countries, there is a market for low quality items. Agree that lack of a manufacturer's logo should be a red flag.

It seems like the manufacturer over-shot a machining process that was meant to make up for the thickness of the cool guy coating. Unless I start shooting pro ( which I will likely never do), I will stick with boring but functional milspec with no super cool coatings.

Yep. The manufacturer was likely using the same parts machined for a hard chrome coating (which can easily exceed .002" thickness) that they used for the titanium nitride coating here (which rarely exceeds .0002" thickness). There's nothing inherently wrong with coatings, especial nitriding, which is actually a case hardening process that doesn't affect dimension much. The issue is that you shouldn't cheap out if your going for the bling like hard chrome or TiN.

They don’t teach it because it’s not relevant to the job. You’re not a gunsmith in the military, you’re an armorer and your job is to swap parts, not make repairs. If a gas key bolt snaps on a carrier, do you replace the bolt or do you scrap the whole carrier out for a new one? See what I mean? It would be inefficient to teach an armory anything more beyond basic troubleshooting and part swapping.
