I'm in need of a few parts for the DPMS .308 AR platform. Used condition is fine, and I'm not too concerned about minor cosmetic blemishes, just as long as they can be safely used again. So, if anyone has upgraded their rifle to a free float handguard and no longer need the standard parts, then I would like to buy your .308 barrel nut, snap ring, spring, and delta ring. The same goes if anyone has upgraded their charging handle and no longer need the standard one, then I would like to buy that as well. I also need a dust cover assembly and forward assist assembly, both also for the DPMS .308 AR.
