Great Lakes® GL-15 .450 Bushmaster Semi-automatic AR-15 Rifle

The Great Lakes GL-15 redefines what a budget-friendly AR can be, boasting precision-machined components made right here in the USA for a price that puts the competition to shame. Built around a great-looking set of 7075 billet upper and lower receivers with a premium Cerakote® finish, the GL-15 can be upgraded with aftermarket parts.

It features an 18" nitrided barrel with 5R rifling that delivers superior accuracy. 5R rifling improves upon conventional rifling by reducing bullet deformation and ensuring the projectile stays uniform during the firing sequence. The barrel is threaded 11/16x24, and comes with a GLFA muzzle brake to mitigate recoil and keep you on-target. The low-profile gas block allows you to replace the 15" M-LOK handguard with any slim handguard of your choosing, and a 6-position collapsible stock completes the package.

With the GL-15, you get all the ballistic performance of the .450 Bushmaster chambering, but in a highly customizable, AR-style package. Perfect for competition, hunting and tactical use, this is the ideal all-around all-purpose MSR.
