I have to deal with my non gun/mechanical friends and thier ARs especially the PSA and fancy cheap stuff. I wont sit here and call it all junk , but some of the shortcuts and where they save money usually end up causing issues.Wow that’s great thanks seems like the same issue thing is junk
Yeah , well something drove you to buy that.I hate to say it but it’s my own fault I should’ve stuck with what I know and should’ve got a good bolt carrier that I’ve had experience with like a BCM
I may have missed it. But did you put another bcg in the upper and see if it functions?The upper receiver is solid with all other bcg just seems like this fail zero carrier is out of spec or poorly built the pistol I built is not my first so I’m going to take it apart and see what’s going on but this bolt is going in pile of parts and already ordered a bcm bolt
How much resistance is a properly-staked gas key supposed to offerIf that’s all that’s wrong with it, that’s not too bad of a fix.
New key, new screws, chase threads, assemble, torque, stake, run it. If you don’t want it, I’ll fix it!!How much resistance is a properly-staked gas key supposed to offer
to someone wielding what is basically a fat screwdriver trying to unscrew the bolts?
Because his visual assessment of the key was that it was adequately staked.
I understand that the bolts weren't properly torqued down because of false friction
from interference by coating contaminating the carrier's hole threads.
And I understand that the key not being sealed against the carrier because of that metal chip
meant that some gas was bled off along the carrier/key interface.
But would properly staked-down bolts not casually rotate regardless of how little
(if any!) torque had been applied during assembly?
Yes a couple different bolts worked fineI may have missed it. But did you put another bcg in the upper and see if it functions?
Nie mój cyrk, nie mój BCG.New key, new screws, chase threads, assemble, torque, stake, run it. If you don’t want it, I’ll fix it!!

unless you displace metal on both pieces the staking will only hold the bolt from turning , after lots of vibration the stake can wear enough for the screw to come out.How much resistance is a properly-staked gas key supposed to offer

I did not want to say anything, especially in the light of other thread of cheapest ar builds, but, using cheap parts is counterproductive.Wow that’s great thanks seems like the same issue thing is junk

I feel like the complete upper I purchased from palmetto was a solid choice it’s the fn barrel and the geissele rail I figured spend a few more bucks the fn barrels are top notch I use a 16 inch for my 600 yard range at my clubI did not want to say anything, especially in the light of other thread of cheapest ar builds, but, using cheap parts is counterproductive.
I think most of those guys got screaming deals on good partsI feel like the complete upper I purchased from palmetto was a solid choice it’s the fn barrel and the geissele rail I figured spend a few more bucks the fn barrels are top notch I use a 16 inch for my 600 yard range at my club
Funny thing is I lubed the shit out of it I really go over these things before a range tripSo it seems like the bcg just needs just a good cleaning, heavy lube, and she‘s fine? Some of those coatings will cause exactly what you describe when a bcg is not thorouhg cleaned and well lubed first. I actually had that happen to a titanium nitride coated one last year. I use a thin coat of Mobil-1 pink grease on all my bcgs now.
Did you detail strip and clean the bolt before lubing it. Also Maybe all that lube created a nice bed for shit to stick to. You get these fancy coated things so it works better with out lube or wont rust? I forget why they coat them.Funny thing is I lubed the shit out of it I really go over these things before a range trip
Maybe karma that, prob fixable with some work.Okay I went to the range this morning, and the pistol worked great with 2 other bolt carriers. If any wants a fail zero bolt carrier it’s in my trash in front of my house lol.
