Great Lakes Firearms GL15 Features The Great Lakes Firearms GL15 is chambered in .223 Wylde for compatibility with both .223 Remington and 5.56 NATO ammunition giving shooters flexibility at the range without swapping uppers or barrels. Its 4150 CRMOV nitride barrel runs a 1:8 twist stabilizing a wide range of bullet weights for consistent accuracy across common .223/5.56 loads from lighter varmint rounds to heavier match projectiles. The 1/2x28 threaded muzzle accepts a custom muzzle device for recoil management or sound suppression while the .750 gas block keeps the direct impingement system cycling reliably under a variety of conditions. A billet aluminum lower and forged aluminum upper form a durable tight-tolerance receiver set finished in OD Green Cerakote for corrosion resistance and a distinctive field-ready look that stands apart from a standard black build. The 15.25 M-LOK handguard with a full top Picatinny rail gives shooters ample real estate to mount optics lights and accessories along the full length of the forend while the M-LOK slots keep the profile slim and snag-free for maneuverability. The G-Force GFAB001 Ace of Brace ships factory-installed offering five adjustable positions for a stable customizable cheek weld and shoulder pocket that adapts to the shooter s build and shooting position. A mil-spec trigger delivers a dependable consistent pull for repeatable follow-up shots while M4 feed ramps support reliable feeding and function across a range of magazines and ammunition types. The included 30-round magazine provides ample capacity for range sessions and range days without frequent reloads. Backed by its threaded barrel M-LOK rail and factory brace the Great Lakes Firearms GL15 delivers a well-equipped OD Green AR pistol built for accuracy adaptability and shooters seeking a compact platform ready to run right out of the box.
