"My experiennce with DPMS is save yourself the trouble and fire lap it. It needs it, BAD!"
What does this mean? For the record I just shot a DPMS 308 with a 16 inch barrel brand new. I am familiar with the break in procedure but I decided it wasn't necessary. Because I am not planning for this gun to be a sniper rifle it didn't really matter to me. I shot 20 rounds through it and cleaned it.
