I went out shooting last weekend and started having problems with my SU16. I've had great fun with this gun, and it hasent given me a problem until now. I would shoot 3-4 shots and have a Failure to Extract. Then the next round would come in and smash against the casing. I'd take the mag out, and the other ammo, and I would have to pull the bolt back and let it slam forward for the extractor to get the casing. Then I'd pull back and it would eject. So I figured maybe the extractor had some gunk in it.
So, using the owners manual, I took the gun apart and cleaned the extractor. Now I'm getting a failure to feed problem. I pull the bolt back to catch a round and it hits the feed ramp and jams. I can pull the bolt back and let it slam home and get the round in, but then when I eject it the bullet has been marred from the feed ramp.
So... what gives? I'm lost.
I'm using USGI 30rd mags. All that have worked flawlessly before.
