The Great Lakes Firearms GLFA AR-15 Pistol in .300 AAC Blackout, OD Green (brand part no. GL15300PBODG) is a compact AR-pattern pistol built around a short 7.5-inch barrel for a maneuverable, easy-to-store platform that still runs familiar AR controls. Great Lakes Firearms finishes the threaded barrel in a durable nitride coating for corrosion resistance and easy cleaning, and equips the pistol with an adjustable stabilizing arm brace for a stable one-handed or braced shooting platform. The .300 Blackout chambering is purpose-built for short-barrel performance, delivering solid terminal ballistics from barrel lengths that would leave 5.56 NATO underpowered. Among our AR pistols, the GLFA suits shooters who want a compact .300 Blackout platform for home defense or range use without stepping up to an SBR.
