Rock River Arms LAR-15M A4 450 Bushmaster | 16″ Blued Barrel, Adjustable Stock, M-LOK Handguard

The Rock River Arms LAR-15M A4 in 450 Bushmaster delivers serious stopping power in a modern sporting rifle platform built for hunters and tactical shooters alike. Chambered in the hard-hitting 450 Bushmaster cartridge, this semi-automatic rifle features a 16″ chromoly steel barrel with a 1:24″ rate of twist and a blued black metal finish for lasting durability in the field.

RRA has equipped this rifle with a free-float M-LOK handguard for a clean, versatile platform ready for optics, lights, and accessories. The mid-length gas system and low-profile gas block deliver smooth, reliable cycling, while the RRA Operator muzzle brake tames recoil for faster follow-up shots. The crisp RRA two-stage trigger provides a predictable, consistent break shot after shot.

Ergonomics and control are dialed in with the RRA Operator CAR adjustable stock, RRA overmolded A2-style grip, and an oversize winter trigger guard for use with gloves. The 7-round detachable magazine and lightweight 6.8 lb. profile make this an agile, packable option for big-game hunting seasons where 450 Bushmaster is legal.
