Hot on the heels of the introduction of their LAR-15Ms chambered in .350 Legend, Rock River Arms have announced another addition to their multi-calibre LAR-15M range, with a new hunting AR, chambered in .450 Bushmaster – describing it as a ‘Modern Straight Wall Hunting Rifle’.

LAR-15M .450 BUSHMASTER (Rock River Arms)

Here’s what Rock River Arms have to say about the new rifle:

Colona, IL – Rock River Arms, one of the industry’s most respected names in Modern Sporting Rifles and pistols, introduces a new .450 Bushmaster carbine. This entry into RRA’s LAR lineup was developed as a modern hunting firearm with dominant short- to mid-range capabilities.

The 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.
