so my first time out a bullet casing got jammed in my barrel and blew out the gas rings when i put wolf ammo through it.
last tuesday i went out again and went through about 300-400 rounds of pmc and umc remington ammo and had no problems until i put some ammo made in china through it . it fired about 60 rounds until it stripped a casing and fed a round into the back of the stuck round. i took the bcg apart and checked the gas rings and one of them was blown. so i took it out and lubed and cleaned thebcg. then it started doing bursts of full auto. after i got home i checked the bcg again and my gas key was loose and the screws came out by hand. what do i do? |

The gas key needs to be properly staked. The loose gas key may be the cause, not the result of your problems. Have to wonder about your source of gas rings as well.
This is assuming that by "bullet casing" you mean cartridge case, and "stripped" you mean fail to extract, or damaged in failing to extract. With the gas key problem fixed, which is step one, and everything repaired, you may or may not be able to change what your gun likes and doesn't. I've been very lucky, but some people report strange things. Some guns just don't like some kinds of ammo. |

You might have a bum carrier. I had one that would eat rings and the bore of it was rough. Bought another carrier and issues ceased. Considering your key fell off it does not sound like a high end unit.
There is the possibility that your setup is overgassed. Specs? Is it used? Clean the chamber well and do an inspection. |

I agree with Pushkat, a loose gas key will cause a gas shortage causing short stroking, the gas rings, well check the carrier for any roughness at all inside just to be safe.
Both of my guns, one rifle and one carbine will shoot Wolf just fine although the carbines gas hole was way undersized so I opened it up a little at a time and it functions perfect. You might also check to make sure the gas block is lined up right and that the gas tube is centered and not binding on the gas key. |

Quoted:
the gun was built by somebody and then sold at a gun store. i was told it was brand new and had never been fired. im tired of screwing with it, im going to take it to a gunsmith. Deal with it yourself. There is very little on an AR that an average person cannot deal with. There is certainly not anything on it that you can screw up so bad that it cannot be fixed. It was obviously put together by someone who did not know what they are doing and it is a benefit to you to learn. With nearly 100k in half trained monkeys around here that can tell you the torque specs in their sleep, fixing the things should be a breeze. |
