Just recieced my new dpms lr-308 0n 050709 and I am totally dissatisfied. Took the firearm out the next day after a thorough cleaning and mounting optics for a barrel break-in session. First I shot 6 single shots cleaning between each shot, no problems, yet! Then I began to shot my 2 shot sequence, first shot went great, second shot failed to feed! Well I thought to myself "new gun just needs a few more rounds through it". Man was I wrong, the next three hours ended in disgust. After sleeping on the situation I headed out to the range again the next morning. After spending several hours and trying several types of ammo and varying the number of rounds in the magazine I was still having the same problem. I noticed the only time I had a failure to feed was when the round was coming from the leftside of the double stack mag, no matter the number of rounds in the mag. Also both mags acted the same way. I began checking the DPMS site and found several owners with the same problem. Many complained about the long turn around time for warranty repairs. Can someone suggest a fix and an explination of what is causing the malfunction? Or do ya'll think I should bite the bullet and just send it back for repair. By the way ammo fired was blackhiils, hornady match, hornady tap and winchester, all in 168gr.
