RRA LAR-15M All Terrain Hunter | .450 Bushmaster | 16″

The Rock River Arms LAR-15M All Terrain Hunter is a purpose-built modern sporting rifle chambered for .450 Bushmaster, fitted with a 16-inch stainless barrel and a 13-inch free-float M-LOK handguard. Designed for controlled, short- to medium-range work where big-bore performance is required, the rifle pairs practical ergonomics with a two-stage trigger and an adjustable operator stock. A Vortex Strike Eagle 1-6×24 (priced under $1,000) is a suitable optic for quick target acquisition and close-to-medium-range accuracy on this platform.

Typical applications: big-game hunting in brush or dense terrain, and precision short-range hunting scenarios where heavy-for-caliber projectiles are preferred.
