Have a friend that has a DPMS LR308 18" Barrel rifle. He bought it brand new. He is having an awful time with it. It will not feed every time. Maybe 3rounds out of 10. He got new C-product mags and is still having trouble. looks to me Like the feed ramps are really rough. It will actually Bend the shoulder of the brass and set the bullet back in the case, When feeding a round into the chamber. He called DPMS and they said it was the ammo or the mags. He's tried New mags and about 6 diff brands of 308 ammo.
Any Ideas? I told him to take it back and get a new rifle of an other brand. But thats Just me.
