The Great Lakes GLFA AR-10 .308 Win is an AR-pattern, modern sporting rifle designed for shooters seeking large-bore performance on the range, in hunting applications, or in heavy-division competition. It combines a durable receiver set and a performance-oriented barrel to deliver consistent .308 Win performance in a semi-automatic platform.
The rifle is built around forged or billet 7075 aluminum receivers for rigidity and durability. It uses an 18-inch 4150 CRMOV barrel with a nitride finish and 5R rifling to support accuracy and barrel life, and the barreled assembly terminates in a muzzle brake on a 5/8×24 threaded muzzle. Ergonomics include a mil-spec trigger and pistol grip, a 15.125-inch M-LOK aluminum handguard for accessory mounting, and a multi-position collapsible synthetic stock in black with a recoil pad for shooter comfort.
