Does anybody here have first hand experience with a 3g1 by DPMS in .308? How reliable are they? I have shot dpms rifles before in .223 and a friends LR ..308 24 in. Bull barreled rifle and these shoot extremely well. But I am looking for someone with first hand experience. Also have you ever shot for accuracy off a bench or bipods? Factory loads or handloads. Already paid for one, just waiting for it to come in. Thanks in advance.
