Bushmaster has added a .308-chambered carbine to its growing line of AR-style rifles. The rifle offers law enforcement agencies additional firepower and longer-range capabilities, according to the company.
The rifle is an ORC (Optics Ready Carbine), in Bushmaster vernacular, because it arrives with two half-inch riser blocks for mounting of aftermarket optics. The riser blocks are mounted to the receiver-length Picatinny rail and provide enough clearance above the upper receiver, so the natural cheek weld aligns the shooter's eye directly behind his or her chosen optic.
