You are LIGHTYEARS ahead of any other AR platform based channel I've seen on YT. I've only assembled Two AR15's to date and so far I've learned that 1. in spite of the "cookie cutter" platform, each build will throw you small curveballs and learning opportunities varying from manufacturer to manufacturer... and 2. Regardless of that, a quality build will require the same specifications to be met in key areas no matter the manufacturer, calibre or style. Watching your videos gains the viewer years of experience in literally minutes of view time. Thank You!

These are the best videos. I have learned a lot from just watching Chad. The detail you you get from him about each part, the specs of them & things to watch out for is top notch! Its nice to hear what is wrong and why in detail, not the usual "This is no good" (from Bubba smith) When times improve I definitely have to take some SOTAR classes. Thank you Instructor Chad!

Thank you. I sincerely appreciate your kind words.

[@joelzeramrgassyninja8654]

Very interested to see what people look for on the civilian side. I'm a 30 lvl repairman for the military, and we didn't even use half the gauges he used in just this video. Barrel straightness, firing pin, headspace were pretty much our go to gauges. Again very interesting and cool.

[@LavitosExodius]

This isn't typical civilian haha typical civilian is ok didn't close on a no go gauge so send it. This is more teaching gunsmithing for a living level.

[@seanoneil277]

Joel Zera -- "Mil Spec" as marketing phrase is different from materiel & armament actually built for US military use under Fedgov contract. That would explain what you mention. Also, what you mention does NOT excuse the QA & QC failures Chad found on this upper. PSA didn't assemble this upper under Fedgov contract for US military use. PSA just uses MilSpec as marketing, to suggest parts will fit -- and not a guarantee they are up to duty use by military personnel.

[@jarrodkiser6042]

As a 30 lvl repairman in the military you have all those gauges available. They are just generally not used because most of the rifles function well enough for military use. The gauges you do use are simply trying to be preemptive about what could cause a failure with injury. They want you to inspect an arms room faster not better. Had an E5 ask me to skip steps because I was taking "to long" during arms room inspections. I told them nope no way I was already doing just the safety and not full operation inspections.

[@1014p]

@@jarrodkiser6042never heard of a lvl anything armorer in the Army. Let alone a 30 lvl. That said all these gauges and tools are over kill generally unless you loaded and can justify his per hour fees. Best I see most failures tend to have easy corrections.

I bought an 10.5" upper with the slant mlok handguard, with the same muzzle device. The gas block screw fell out after firing a few rounds and I noticed the muzzle device touches the handguard. I changed the muzzle device and put in new screws. One other thing to note, the barrel was not dimpled, so I went ahead and done that on my own.

Just subbed, I like your work area. I really like all the special tools you have. I’ve never seen most of them. If I could change professions I would enjoy doing stuff with guns. Especially becoming a gunsmith.

[@tomilove3856]

Starting about 7 years ago I bought a complete PSA M4 clone. It was very good quality, cycled flawlessly and shot about 1.5 moa. A year later I purchased a 10.5 upper without the bcg and charging handle. The upper was so badly out of spec I couldn’t get a charging handle in the upper regardless of manufacturer. I tried four different charging handles including a mill spec. All of them worked on my other uppers. F marked front site was badly canted. It still cycled but I almost ran out of windage adjustment zeroing it in. Fast forward to last year I bought an 11.5 phosphate upper and it was perfect. I just purchased a stealth lower and complete 11.5 nitride upper a couple of weeks ago and it looks outstanding. It would seem as though they’re QC is getting better

[@209brandonb]

I’m hooked on your channel I watch so many of your videos I’m starting to talk like you!! last night I told my wife I’m going in through the muzzle first!!!

[@45shfifty]

I've owned a few PSA AR prebuilt uppers and had no issues with any of them

[@southerndarkness9922]

Yeah I have many of all lengths in the nitide and non lined uppers as well as the fn uppers and all are great.

[@onpsxmember]

You have a very small sample size. Hasty generalisation fallacy. Because your few were running doesn't mean it's the same for most of them. If you watch a particular barrel autopsy also from SOTAR, there is a former psa QC worker that mentions some years where the QC was worse, people got canned and they source and produce more themselves now. So let's say you'd fall in that category and had a few that sucked. It would again not be sufficient.

[@JD-tn5lz]

One, you've been lucky. Two, how many thousand rounds have you put through them? Three, what is your shooting protocol? Do you push yourself and your PSA rifle, what are the limits? Four...any bad manufacturer/assembler can produce a reliable rifle and any good manufacturer can produce a lemon. One of my favorite ARs ever was an Adam Arms. I drove it like a stolen car and it stood up. However, I bought it dirt cheap and I know I Got LUCKY! Don't let love of a price point cloud your judgment. If you love your life and you honestly believe your life may depend on you operating a machine, get the best machine you can afford. Would you trust your truck mechanic to work on your ride if you noticed he only bought the cheapest tools made in China?

I have a PSA upper with the FN barrel and geissele gas block, rail, amongst other goodies. Thing runs like a champ, but the base palmetto I got on sale with BCG plain jane required me to change my buffer weight. Dunno, I trust PSA. Decent prices for good products. I know people poopoo on them but most of the time they do a bang up job. Thanks for another fantastic video, Chad. I love your autopsies and physicals. I can watch those for days!

[@robertfoote3255]

They make a LOT of budget AR's.... that said a metric of how many per 1000 or a nother benchmark would be a better analysis... I have several of PSA's rifles and the only issue I had was a out of spec hand guard.....and they promptly replaced it and payed for shipping... I have better rifles....but I find they are a good value for there price...not every rifle needs to be a battle rifle to make someone smile...

[@itsfree2639]

@Paul Barclay Bcm doesn’t make any parts. They are an assembler. Nothing is made by them...

Doing a cheap job with questionable QC is not really what most folks would call "a bang-up job" -- unless being sarcastically ironically punny.

[@Z33Garage]

These videos have made me so paranoid about my guns LOL. I havent had issues with my PSA parts when I bought and assembled them, but having seen this I will go though my guns and look for the key issues you showed ( at least what I can check without those gauges)

[@yeshua1176]

Same my 10.5 psa upper has been flawless with about 300 rounds thru it so far my new 16 inch mid length upper on the other psa has not been fired yet going to thoroughly look them over after seeing this

Best to get yourself a good AK. Nothing on those require gauges other than head spacing. You buy one, take it to the range, make sure the barrel is free of cosmoline and voila! You have a perfectly good rifle that will last generations before needing a cleaning.

[@JD-tn5lz]

I understand budget concerns and the appeal of PSA pricing and marketing...however. Not that other manufacturers don't have problems also, but sometimes, just sometimes, you get what you pay for. For example, I personally have had persistent problems with Ruger ARs (decided that they were only toys, not for real world) and I've heard so many horror stories about PSA and have seen some real junk from them. Save your hardearned money for something that not only you can trust, but something you can proudly show off. I'm saying that if you're a serious shooter, spend serious dollars. Go find an LMT, LWRC,DD, FN, Adcor, KAC, or an old Colt...something somewhere that has true milspec parts and survived modern military testing. All those mentioned above have been adopted by someone. Or, admit that you just want a "cool plinker" and enjoy it, but understand it's limitations.

[@impactaustria]

Thank you sir, for providing all these very interesting, educational, insightful and helpful videos! I'm curious, what would have been the things you would have checked if you had been able to disassemble the upper and which things typically have the larges impact on good/poor accuracy there? (barrel extension receiver fit, barrel nut torque, perpendicularity of receiver and inner barrel extension face (the surfaces that wedge the extensions shulder) poorly fittet extensions, damaged crown, misaligned muzzle threading, maybe a loose gasblock.....?)

[@broznkyra4853]

Thanx for the views of the 'reaction rods'...finally getting to see what they look like..I have an original Peace River upper assy clamp...Peace River produced them for a while and sold them here in So FL until they went T U in the mid 90s...Brownells bought the design and sells them with the Brownells logo but I have an original...I like the reaction rod...and if I get the money/opportunity Ill get one...

[@broznkyra4853]

Peace River also sold a number of custom AR rifles with laminated wood stocks...as a sort if "kindler/gentler AR" in anticipation of the 94 AWB..they sold a few before going T U...leaving many disappointed/angry customers who had put deposits on them...I bought a 'Glenwood' model from an estate sale...have only seen one or two anywhere ...including on line auctions...has anyone else ever heard of those ARs???

I dont have a pivot guage but the too wibbkesca whole lot. I replaced the one with Geissele automatics pubs still the same hand to get creative and just use some automotive clearcoat to paint the inside of the rear hole for that take down pin. It diesnt shake anymore but I can see light in between the upper and lower. Thhs hs my secing osa build and I wasn't thrilled with the way it held together with the stock oubscontiba very good aero M4E1 lower so my guess is its PSA upper why it's not connecting to my Dark storm lower 100 percent. Since I fixed the wobble it's acceptable but I've put so much money until this sbr with other parts for it not to be perfectly inline. I've replaced almost all the PSA parts with either Geissele aero tube rise arrangement trigger but I have to say that trigger wasnt bad at all. Neither was the bolt catch. The safety selector in reolacingvwiksin combat aanecwurh charging handle Geissele super 42 spring and h2 buffer titanium detent PSA brand Guntec castle nut enhanced qd end plate and Geissele maritime bolt catch and take down pins battlearms group mag catch and mag button and spring ergo pistil grip. Daniel Defense stock I wanted to go for an mk18 style so I'm trying to get on the Daniel Defense handguard but like I said Palmetto decided to epoxy it on I have no idea why and I want to out on my Strike industries king compensator or my 2a armament who knows though will I need a different delta nut or some type of heatccover PSA doesnt want you to alter these parts but I'm tired of seeing a flash cone and I never was a huge fan of the slant handguard.

I always look for ARs that have been adopted by militaries or reputable law enforcement agencies.

Thank you for sharing you info. You have me wondering at 9:45 when you bring on screen a "non magnetic washer" then test two components to see if they are magnetized. Well if the that washer is non magnetic no magnet would pick it up. So I''m not sure what the purpose of this was? Cheers, Billy in Canada.

[@lesliestar6344]

I thought the same thing. Perhaps he "just miss-spoke".

[@workingguy-OU812]

My only guess was to make sure that none of the AR parts were magnetized - magnetized parts would have iron dust stick to them.

[@bills6093]

He meant non magnetized washer. Such that if the washer sticks to the bolt, it indicates that the bolt is magnetized.

[@Gronicle1]

A lot of people shoot cheaper "steel case" ammo in these guns. Having a magnetic bolt could cause FTF or FTE issues.

[@ichetuknee]

Please see my reply to Mystery Meat. The object must be paramagnetic, so that it cannot hold a permanent magnetism and thereby be the cause of sticking. Nevertheless, it must be capable of being magnetized temporarily when a magnetized test object is brought near.

[@nathanielradtke7590]

Could very tight headspace and excessive firing pin protrusion cause a big problem- out of battery discharge?

[@JD-tn5lz]

I'm sure I'll be burnt at the stake for this, but this is should be expected from any assembler claiming they're a manufacturer and selling to the low budget line. Every PSA I've seen has not stood up to hard Alaska use and some not even to summertime playing. If you want a sub-1000rd/yr plaything cheap, buy PSA and enjoy. If you want something to be proud of, go work some OT, save your dimes, and get something from someone reputable.

[@benningsniper9516]

If anyone has a problem with what you've said, I can't understand them. I took a PSA to thunder ranch and it lasted 2 days. I finished the course with one of their house rifles. I came home and immediately bought a Larue OBR. It has been to thunder ranch and two other courses, and hasn't skipped a beat, other than shooting lower grain ammo like a shotgun. 70+ gr ammo groups less than a minute reliably, so that's weird. My point is you're 100% correct. Decide if you want a toy or a tool. You're going to pay for a real tool, and companies like PSA don't sell them.

It will be fine. It is no precision rifle, but for the money it won't do you wrong. I have over 5k through each of mine. Shoot about 2-3 MOA. Not the prettiest craftsmanship but they work. You get what you pay for, and for the price it is alright.

K Watson mine has a canted fsb

So, I now I get that why he tests the bolt and bolt carrier for magnetism only applies to steel cased ammo. Now I'm guessing that if the bolt was magnetized strongly enough ... it might interfere with ejection of steel cases ?

[@EarthAltar]

I think more of an issue with a magnetized bolt and the use of steel casings would be a build up of iron fillings on the bolt face and lugs. That could cause a host of FTF and FTE problems, and who knows what else.

[@boxwoodgreen]

@@EarthAltar Thanks ! That does make more sense.

[@FirstLast-Sandman]

Very educational, thank you sir!

The erosion you refer to where the gas hole intersects with the ID of the barrel is more likely drill breakout when that hole was drilled during the machining process. That jagged edge is almost impossible to prevent when drilling through holes. However it can remedied or reduced with a deburring process, post drilling.

[@seanoneil277]

Nope. Not at all hard to prevent if your work piece is fixed, your bit is sharp, your press & table are not misaligned, and your feed is patient.

Where does one get that upper receiver bore light you use ?
