Send me the entire upper and I'd do it free of charge so long as you/he pays the return shipping of the upper. I'd also remove and remount the carrier key and install better screws and stake it correctly. I recommend using a BCM SOPMOD extractor upgrade kit also which includes an extractor, ext. pin, ext. spring, black ext. buffer and o-ring and a new set of gas rings.

Out firing the other day we brought steel cased ammo. Cheap at cabelas so don't burn me. Anyways the gun cycles the fmj fine but sticks casings and blows primers on the HP stuff. Now I know that its Def the ammo there but my first question is if Ned's 5.56 reamer would fix this? My next question is if someone nears south Dakota would be as so kind to let me borrow theirs. Or if someone would be willing to mail one to me for his barrel?
I do understand that the moral of this story is friends don't let friends buy crap ars.
