Well the good new in the magazine department is that CProducts is now making SS 20rd mags for the DPMS LR308 series of rifles.
Both my .308s by DPMS are very accurate. The 16" barreled AP4 will shoot just over moa at 100yrds with match ammo and 1.5moa with the Hornady TAP line of ammo. Surplus 7.62 goes anywhere from 1.8" to 2 1/4" at 100yrds but that's machine gun ammo.
The 24" LR308 with 10x glass, two stage trigger, prs stock, bipod, and Federal "Gold Match" 168gr BTHP will put 5 rounds into one ragged hole, .48", at 100yrds. Okay so I did that once but with the Hornady 110gr, 155gr, and 168gr TAP AMAX it will put 5 rounds into .78" to .80" if I do my part. You can go to the DPMS website and see some targets people have posted there, they're very accurate out of the box rifles.
