The GLFA GL10 LA in .300 Winchester Magnum represents a breakthrough in AR-platform engineering, delivering magnum rifle performance in a familiar AR-10 form factor. Built around a patent-pending action design, this rifle features a 24" match-grade barrel crafted from 416R stainless steel with precision 5R rifling and 1:10 twist rate. The platform incorporates 7075 billet aluminum receivers paired with a 20" M-LOK handguard system, offering full-length Picatinny top rail for optics mounting. A custom-designed bolt carrier group and charging handle work in concert with the rifle-length gas system to manage the substantial power of the .300 Win Mag cartridge. The rifle's 45.5" overall length and 9.25 lbs weight provide excellent balance and recoil management, enhanced by the 5/8x24 threaded stainless steel muzzle brake. Key features include a Hogue fixed rifle stock, mil-spec trigger with 5.5-6 lb pull weight, and custom-designed 5-round aluminum magazine. The GL10 LA maintains compatibility with standard AR-10 lower parts kits while delivering magnum rifle ballistics. This innovative platform bridges the gap between traditional AR ergonomics and long-range magnum performance, making it an ideal choice for serious hunters and precision shooters demanding extended range capability in a modern sporting rifle format.
