That's Springfield Armory's SOCOM II Rifle. I've played with them. Sweet little rifle. But I don't like a 16 inch .308 Rifle. You waste alot of the energy from the round. In my opinion, either a 18 inch or 20 inch barrel on those M1As are a good platform. What a shame they don't offer the SOCOM II package on their Scout Sqaud Rifle.
