It's a DPMS AR-10 and the break in was after the first 10 Rounds, clean the bore. Each consecutive time up to 50 rounds and then every 25 rounds until 200. I did this and got jams. I read where DPMS said do not foriegn ammo so I stuck with American made ammo. I used plenty of breach and bore lube every time I shot. Being retired army I remember using tons of REM oil on the M16a1, A2, and last the A4. The jams have to be from the extractor pin. Something is not right with it.

I am having an issue with my AR10 and feeding problems. I broke in my 308 the way it was suggested. I had jam issues from the start. I changed ammo, magazines, had a gun smith look at my rifle, no luck. The jam happens after every 6-8 rounds. It double feeds and even bent a round this last time shooting (22 August 2015). I am attaching a picture of the ammo I used from Lake City Ammunition MFG. anyone can help me with this issue and know who I can contact?
