Had this happen to one of my uppers, took it to my LGS (where they pride them selves on their AR builds) and all I wanted was for them to swap out my hand guard. When I came back to pick it up they said it was a PITA to get the original one off, and when they handed me my AR I cycled the bolt to check that the chamber was clear, and it stuck to the rear with no mag. Luckily the guy that was there when I dropped it off verified to the manager that the bolt was cycling just fine when he checked the chamber when I dropped it off. After a few minutes in the back with my AR they came out and told me that their guy must have crushed it in their jig, and they immediately said they would replace it at no charge with the same brand. I didn't make a stink since they fessed up without me having to complain, and since the gun never left the store. While I never brought anything back to them to be worked on, I did continue to shop there and shoot at their range and they have always been friendly to everyone I've seen walk through their doors. Anyway, sht happens so try not to get pissed right away because sometimes it works itself out.
I know it is a small and very honorably thing but man it is nice that you don't bash on mfg's for every issue you encounter. It is what makes videos like this go from good to great.
I've had two M&P 15 Sport 2's. My neighbor also has one. All three have receivers bent in the same way. On one, it caused malfunctions until I bent it out enough to relieve the resistance. The three guns were made years apart, between 2016 and 2022.
Could you repair the bow by inserting a mandrel with the contour of the BCG and gently expand the diameter of the bcg via a set of tapered wedges . Like a dent removal tool for a shotgun barrel? Also, would you recommend using a heat gun to warm the metal to lessen the susceptibility of cracking?
😂 I just asked a question on another video about a scratch in one of my barrels. I ordered a PSA upper and that upper was crushed more than that one. I had to pretty much force it in. I worked it a few times and it's not as snug but still doesn't move freely 🤦. Guess I have to send it back.
Got my hands on a colt a2 upper from a guy whose wife went to town on it with a hammer in a fit. It was crushed pretty bad and took substantial effort to get the bcg out. Ended up reaming it out and it now lives on a meme rifle.
@@investigativeoutcomes9343 Not if you stay within the proper torque values. The lugs on the reaction rod are aluminum, and will give before the steel lugs in the barrel anyway.
@@EarthAltar Wrong. Too many ways to show you you’re wrong to list, but go ahead and try to put on a URX4 handguard using a G RR and then with the MI version. The MI is just so much better.
Funny I'm watching this in about a week and a half ago I just barreled an upper. I only use a two piece vise block that not only clamps the outside but there's an insert that goes in where the bolt carrier and charging handle rides and fills that whole void to reinforce it internally.
Idk about the sports but I have m&p 15 from 2006 while under stagg arms if im not mistaken. Best AR out there NOOOO definitely not. However It does stand up with some of the big boys out there to this day.
What causes an extractor pin to shear? I had no problems at the range today but when I got home to clean my ar and take it apart I was shocked. As I took apart the bcg I saw a bunch of little circles of metal. My first thought was I must be punching through primers because I had that problem on a different ar. But as I removed the pin for the extractor I quickly realized that the pin was half the size it should be and those circles of metal must be from it.
extractor may have gotten "stuck" sticking out a little. Dirty? Anyway, it causes the pin to stick out ever so slightly when it should be fully retracted. When the BCG picks up a round the butt of the casing is sliding into the bolt and shearing the pin where it's protruding out, this is how you get the small circles. Most likely it ran out of lube, or was dirty, or there is a manufacturing defect(rut?) causing the pin to not fully retract (bind) inside the bolt.
@@Oldmankingspiffy Sorry my friend, "dirty" isn't just referring to how often the rifles was cleaned. Even after a single shot it is possible to get dirt, or even metal shavings that interfere with the firearm's normal operation. Given the small slivers of metal you mentioned, it is a 100% guarantee something caused the extractor pin to protrude outward just far enough to get shaved down during cycling. It wasn't a knock as to your cleaning regiment, as over cleaning can actually cause the same kind of "out of round" wear that can cause the extractor to bind up. To solve over cleaning issues, I only clean my rifles after roughly every 150 rounds, or if the rifle will be stored without use for extended periods. even this may be a little more frequent than what is necessary.
Not sure who else to ask but I figured I'd ask on here. When I'm doing a fast reload on my BCM while the bolt carrier is back, the trigger is not engaging. It engages fine when I shoot regularly but when I try to do a quick reload while the bolt is back and then press the bolt catch to lock the bolt carrier in place, it does not shoot? Can anyone help me out, it's driving me crazy and this is a brand new weapon, also the magazine seems to get stuck and very hard to get out. I have to force the magazine out with a lot of muscle.
Hello, i have an Fm15 gen 2 with almost 800rd on there. Anyway i can send it over for an inspection? Has some pretty uneven wear as you can imagine, wanted to see your opinion on the system if possible. Thanks!
Really? I've put 400 rounds through my Palmetto AR and have not a single noticeable amount of wear. You literally can't even tell this weapon has been fired after a cleaning. there is not a single point of wear anywhere on the rifle other than a small blem that was there when I bought the receiver as a blem lol. I'm going to say your rifle is out of spec, or is having some other similar issue.
You should definitely have it looked into, because I can almost bet it's out of spec from the manufacturer, may have a lifetime warranty like palmetto. Just to note: I clean and re-lube my rifles every 150 rounds or so.
@@teksatan4699 well this was after the 500rd break in. I guess. I should've included this, so basically 1300rd I ran the hell out of this gun, a few hot cycles in a very sandy dirty area. Only about 3 hard range days and a few long range days at the sitting range. I wouldn't say it's wearing down horrible, but you can see where the finish is being removed. My palmetto has some love scars lol, runs like a horse though haha
You need to get yourself a XRF PMI Gun (Alloy Analyzer) so you can ID exactly what material was used to make the part(s). You will find about 90% of the aluminum AR-15 parts sold as 7075 are actually much cheaper/softer 6061.
Thanks for not calling out the manufacturer. It's about the learning experience, not the brand.

And always check your repairs before you leave the shop, no matter what you were having worked on.
Thanks to this channel I just finished my first build with enough confidence to test fire
Yeah, you can see the bend below the dust cover. This channel is awesome. 👍🏽

Quit sleeping on you rifle.😅
Another good training example!
Thanks for sharing!
Now I’m checking my new receivers thanks
I'll be doing a check now. Thanks Chad
Slow is smooth, and in this case, smooth is the gauge.
Usage of the correct bench block is priceless,,,,,,,
Semper Fi,,,
what bench block do you think is the best one, or which design do you think is the best?
do you think the reaction rods are good?
Could you repair the bow by inserting a mandrel with the contour of the BCG and gently expand the diameter of the bcg via a set of tapered wedges . Like a dent removal tool for a shotgun barrel? Also, would you recommend using a heat gun to warm the metal to lessen the susceptibility of cracking?
Yes
I really wish more companies would start using the midwest reaction rod for their installation.
I had the same issue when I was new to AR’s and was able to fix it and has run fine since.
How did you fix it?
Can you do a video on low profile gas block and gas tube leaks and proper installation?
😂 I just asked a question on another video about a scratch in one of my barrels. I ordered a PSA upper and that upper was crushed more than that one. I had to pretty much force it in. I worked it a few times and it's not as snug but still doesn't move freely 🤦. Guess I have to send it back.
Thank you Sir.
Looking forward to more vids.
I love this show!!!
This is why you should use a reaction rod and never not a reaction rod!
Except not a reaction rod and yes a Midwest Industries with the “sail”
Got my hands on a colt a2 upper from a guy whose wife went to town on it with a hammer in a fit. It was crushed pretty bad and took substantial effort to get the bcg out. Ended up reaming it out and it now lives on a meme rifle.
Simple, but extremely helpful to know. Thanks!!
That's why a reaction rod in the vise is better than your upper in the vise.
Midwest Industries’ with the “sail” is way better than the Reaction Rod, though
do you think it is possible to damage the lugs with a reaction rod?
@@OFFICIALUND whoa, i have never heard of that one.
@@investigativeoutcomes9343 Not if you stay within the proper torque values. The lugs on the reaction rod are aluminum, and will give before the steel lugs in the barrel anyway.

SOTAR can you do a vid on tweaking it back into specs
That's what I was hoping to see in this video!
My left ear thanks you.
Great info thanks
I did that to one of mine. Tweeked it back with two wrenches. runs like clock now. Bought a reaction rod the next day
Is there a way to fix it? I crushed mine, I replaced it but could I fix the stripped upper or is it garbage
Q.C. at that manufacturer needs to check his gauges and or his eye sight !
Another great video from the School of the American rifle .
If this gets by they don't have QC
i think it was operator error
👍😊 good to know.

Use of the wrong tools results usually in damaged products no matter what your building.

It probably was run over by Rob Ski at AkOU.
