RRA LAR-15M .450 Bushmaster produces new advantages for modern hunters using straight wall cartridges. Delivering the same 1 MOA @ 100 yards accuracy expected from RRA’s precision rifles, the .450 Bushmaster features a 16-inch stainless-steel cryo-treated barrel with smooth rifling (1:24 twist) and equipped with an RRA Operator Brake. The RRA two-stage trigger provides a crisp break and is housed in the RRA winter trigger guard, allowing full dexterity while wearing gloves.

The RRA LAR-15M .450 Bushmaster comes standard with a six-position Operator CAR stock, overmolded A2 pistol grip, and 13-inch extended lightweight free-float handguard covering a low-profile gas block and mid-length gas system. The full-length top rail configuration fits all quality optic systems while the M-LOK compatibility provides for accessory attachments, such as a bipod and light source. A sturdy hard-plastic, five round polymer magazine, owner’s manual and warranty are included with the rifle.
