The LAR-15 CAR A4 features forged aluminum receivers with a flat top optic-ready upper to give you the strength and durability that you expect in a modern sporting rifle. It comes with a carbine length drop-in handguard, an RRA Tactical CAR buttstock and an RRA overmolded pistol grip to give you the perfect fit and great control. Chambered in 5.56 NATO, it also accepts .223 Remington with a sturdy A2 front sight gas block to keep you on target. This versatile multi-purpose rifle has Rock River's excellent two stage trigger, a 16" chrome moly barrel with a 1:9 twist and an A2 flash hider. Affordable and exceedingly effective, the LAR-15 CAR A4 from Rock River Arms offers fantastic performance in any shooting environment! Rock River Arms makes some of the best AR-15 rifles in the world. After exhaustive testing, both the FBI and DEA turned to Rock River Arms for their patrol rifle contracts. If you want a rifle rugged enough for the top federal law enforcement agencies in America, choose a Rock River.
