I shot my new Pre-Ban AR15 today. It would only allow me to shoot once and it would not eject the cartridge and attempt to load the next one. Once I took out the magazine and pulled the bolt back, it would eject it. It would do this everytime. I was wondering if you guys have any thoughs on what the problem might be. Thanks!!

If the ammo is decent stuff that works in other AR's, and the chamber isn't damaged or too filthy to function, then check the gas system. 1. make sure the rings in the bolt are NOT all lined up. 2. if that isn't the problem, replace the gas tube. 3. if it still won't work, remove the front sight and clean out the holes in both the sight and barrel. If you think the mag has something to do with the problem (unlikely), try loading a single round, removing the magazine, and THEN firing. If it extracts, then maybe you have a magazine that's way too tall and is jamming things up.

I believe the gas tube and hole is self-cleaning. I have shot many rounds of the dirty 22LR thru my AR and I had no problem switching back to 223Rem. Functions just fine. Maybe try diferent combinations of ammo and magazines. If you still can't figure it out, call Bushmaster for a authorization to return your gun to them and let them check it out.

I just received two extractort pins from Ed at Gunsmoke (free of charge). He told me that it sounds like I have a weak extractor pin. I'll soon find out.

A buddy came with a BM VMatch heavy varmit barrel and he said it was a single shot because it would not eject the casing and if it did it would not pick up another round....I thought it may be his rings...when i pulled out the bolt 2 of the rings were lined up---Is that enough to cause faulty operation as described above??????????

The AR15 design has been known to function WITHOUT gas rings. The myth about the gas rings lining up and causing a malfunction is absurd.

i'll go to the range before the weekend is over and i'll report back on how BM does with the rings not lined up.........Dick

Try cleaning your rifle of all existing grease and powder. Then try lubricating the action with corrosion block lubricant. It's a blue colored lubricant that is very good and does not gum up. Also try using colt magazines. I hope it helps you out. It works for me. Good luck.

It could be the extractor slipping off the rim. I just changed the spring on that one and solves the problem. Another problem can occur is the ejector could be frozen. I found a small piece of metal in the ejector spring. Does anyone knows if that D ring product works?

I had the exact same problem with a new pre-ban upper I purchased directly from BM. Upon manually ejecting the 6th round, the front bolt carrier key screw ejected out of the weapon as well. I sent it back, they fixed it promptly, and it has worked very well ever since.
