Great Lakes GL15450BLK | .450 Bushmaster | 18″ 5rd

The Great Lakes GL15450BLK is a purpose-built modern sporting rifle chambered in .450 Bushmaster with an 18″ barrel and a black Cerakote finish. It ships with a single 5-round magazine and mil-spec controls on 7075 aluminum billet receivers. For a rugged, versatile optic under $1,000 that pairs well with this platform, consider the Vortex Viper PST Gen II 1-6×24 for fast target acquisition at close to moderate ranges while retaining precision for follow-up shots. This rifle is suited to short- to moderate-range big-game hunting and thick-woods brush work where a heavy, straight-walled cartridge is preferred.
