The Great Lakes Firearms AR-10 .300 Win Mag is a precision rifle built for long-range hunting and high-power target shooting. This 24-inch stainless steel platform combines the proven AR-10 platform with the stopping power and extended range of .300 Winchester Magnum—a caliber trusted by hunters pursuing big game at distance. At 10.2 lbs, it strikes a balance between portability and stability, making it practical for field work without sacrificing the heft needed for consistent accuracy on demanding hunts.
Built on a billet aluminum lower and upper receiver, this rifle comes equipped with a 20-inch aluminum M-Lok handguard that accepts standard Picatinny accessories for optics, lights, and other tactical gear. The 24-inch barrel features 5R rifling with a 1:10 twist rate, cut from quality 416R stainless steel to handle the pressure and heat of magnum loads while resisting corrosion. A custom-design bolt carrier group and charging handle come configured and ready to function out of the box, while the rifle-length gas system provides reliable cycling across factory and handloaded ammunition.
The fixed Hogue black stock keeps things simple and solid, with a standard grip for familiar ergonomics. A 5/8 x 24 stainless steel muzzle brake helps manage recoil—important when you're behind a magnum. The included 5-round magazine is designed to feed reliably through the GLFA platform. This is a rifle for shooters who know AR ergonomics and want the modularity of the AR-10 system without compromise on power or range.

This rifle is chambered in .300 Winchester Magnum, a potent long-range hunting cartridge capable of taking medium to large game at extended distances. The 24-inch barrel and 1:10 twist rate are optimized for this magnum caliber, giving you the velocity and energy needed for consistent, ethical hunting at range.
Yes. The GLFA AR-10 platform uses a standard billet lower receiver and is compatible with AR-10 lower parts kits and triggers. The M-Lok handguard accepts standard accessories, and the rifle-length gas system operates on proven AR-platform principles. If you're familiar with building or upgrading AR rifles, you'll find familiar territory here.
The rifle ships with a custom 5-round magazine. The fixed stock, muzzle brake, and bolt carrier group are all installed and ready to use. You'll need to source an optic and mount separately if you don't already have one.
At 10.2 lbs and 45.5 inches overall, this rifle is reasonably portable for a magnum platform—heavy enough to manage recoil and deliver stable shooting, but not so heavy that it becomes a burden on long days in the field. The stainless barrel and billet construction ensure durability for backcountry use.
