The Bushmaster XM-15 16" Heavy Barrel Carbine provides heavy-duty performance whenever duty calls. The heavy profile 16" chrome moly vanadium steel barrel is manganese phosphate-finished to insure protection against corrosion and rust, and the carbine features a threaded birdcage flash suppressor and a 6-position telescoping stock.
The upper and lower receivers are machined from 7075-T6 aircraft aluminum forgings for light weight and added strength, and the upper receiver is offered in A2 and A3 configurations. The A2 upper receiver (SSI 13233) features a fixed carry handle and has a 300-800 meter rear sight system with 1 MOA elevation and 1/2 MOA windage adjustments.
The A3 upper receiver (SSI 13232) features a Picatinny rail, a removable carry handle, and a 300-600 meter rear sight system with 1/2 MOA elevation and windage adjustments.
The carbine ships with a lockable hard case, an operator safety manual, a chamber flag, a sling, and a 30-round magazine.
