Rock River Arms LAR-15M ATH 450 Bushmaster Semi-Auto Rifle – 16″ Barrel, Adjustable Stock

The Rock River Arms LAR-15M ATH in 450 Bushmaster delivers hard-hitting performance in a modern sporting rifle platform built for hunters and serious shooters alike. Chambered in the powerful 450 Bushmaster cartridge, this semi-automatic rifle is engineered with premium components that set it apart from the competition.

At the heart of this build is a 16″ chrome-moly barrel with a 1:24″ rate of twist and a stainless steel metal finish, optimized for accuracy and durability with heavy-caliber projectiles. The mid-length gas system provides smoother cycling and reduced felt recoil, while the low-profile gas block keeps your sightline clean and unobstructed. An RRA Operator muzzle brake further tames recoil, making follow-up shots faster and more controlled.

The RRA free-float M-LOK handguard offers a rigid, lightweight platform for mounting accessories such as lights, lasers, and bipods without interfering with barrel harmonics. A Hogue rubber pistol grip provides a confident, comfortable hold in all weather conditions, and the RRA Operator CAR adjustable stock allows for a customized length of pull to fit a wide range of shooters. The oversize winter trigger guard ensures easy access whether you’re wearing gloves in the field or at the range.

RRA’s renowned two-stage trigger delivers a crisp, consistent break that enhances precision shooting, making this rifle equally at home on the hunt or in competition. The 5-round detachable magazine keeps the package compliant in restricted-capacity states, and the black synthetic furniture paired with the stainless-finish receiver gives this rifle a clean, professional look.
