hello there. i'm a novice AR guy and i'm looking for some help on an ejection problem i have somehow developed.

it seems that the spent casing is getting hung up on something and isn't ejecting completely before the bolt starts to move forward, then the next round becomes jammed. i have a short video of the failure, see the following link.

http://youtu.be/eYb0lRCu26o

the rifle is a DPMS .308 with about 700 rnds through it; the rifle is pretty much stock except for the iron sights and the muzzle brake. i started to get this ejection failure late in the day after 250 rnds of flawless performance. a couple of the guys i was with checked the ejection pin pressure and the ejector claw, both were deemed operational. the gas block doesn't seem to be leaking either. i was told it might need to be cleaned, but i clean it thoroughly after each outing; shouldn't i be able to go through more than 250 rnds between cleanings?

any ideas on what i should do?

thanks for your time.

different ammo?

sounds like weak rounds. what changed now in all the previous rounds being shot? need more lube? try that.

A close up of the failure would be really helpful.

What type of ammo were using, magazine? Close up pics of the chamber and bolt?

I would bet ammo and not enough lube.
