Great Lakes GL10LA300SSBRZ | .300 Win Mag | 24″ | 5rd

The Great Lakes GL10LA300SSBRZ is an AR-style, semi-automatic modern sporting rifle built for .300 Winchester Magnum performance in a 24-inch stainless threaded barrel. The rifle pairs a bronze Cerakote finish on billet aluminum components with a 20-inch M-LOK handguard and Hogue fixed stock for a stable, familiar platform. For optics, a mid- to long-range riflescope such as the Vortex Viper PST Gen II 3-15×44 provides a durable, glass-quality option under $1000 that suits the cartridge and barrel length.

Applications for this rifle include precision shooting at extended ranges and big-game hunting where the .300 Win Mag’s terminal performance and a 24″ barrel are appropriate.
