Great Lakes Firearms and Ammunition AR-15 Bronze/SS .450 BM 18″ Barrel 5-Rounds

GLFA AR-15 .450 Bushmaster Features

This model is optimized for performance with modified M4 feed ramps for reliable feeding and a 0.750 gas block paired with a mid-length gas tube for smooth operation. The Mil-spec, polymer grip and a 15.25″ Aluminum 6061 handguard with a full Picatinny rail provide a solid foundation for customization, without the inclusion of ambidextrous safety features. With a magazine capacity of 5 rounds and one magazine included, it meets the needs of hunters and shooters alike.

The muzzle brake’s unique design, projecting gases 6 degrees forward, significantly reduces recoil, allowing for tighter groupings without the need for Loctite. While the rifle lacks sights, this offers shooters the flexibility to mount their preferred optics on the expansive rail space. The Mil-spec trigger, with a 5.5-6 lb pull, ensures consistent firing performance.
