Great Lakes Firearms GL15 Features The Great Lakes Firearms GL15 runs a direct impingement operating system paired with a 4150 CRMOV steel barrel finished in Nitride for corrosion resistance and long service life. Its 1:8 twist rate stabilizes a wide range of .300 Blackout bullet weights from lightweight supersonic loads to heavier subsonic projectiles giving shooters flexibility to run whichever load suits the task at hand. A muzzle brake reduces felt recoil and muzzle rise keeping the compact pistol controllable during rapid strings of fire even with the shorter 7.5-inch barrel. The 7075 aluminum billet lower and Mil-Spec trigger provide a solid familiar shooting platform for AR-pattern shooters and the .223 Wylde-compatible chamber lends the action added versatility for those cross-training on other calibers. Wrapped in a durable Black Cerakote finish the GL15 resists wear and corrosion through repeated handling and field use keeping the aluminum receiver protected across years of range trips and daily carry. The 7-inch M-LOK handguard offers ample real estate for mounting lights lasers or vertical grips to suit the shooter s setup letting the pistol be configured for home defense range work or truck-gun duty alike. It ships with the GForce Arms Adjustable Ace of Brace pistol brace giving shooters a stable point of contact without the need for a separate purchase and helping manage recoil during one-handed or braced shooting. A single 30-round polymer AR-style magazine is included giving this compact pistol serious capacity right out of the box and rounding out a package built to be ready to shoot as soon as it arrives.
