The GLFA AR-15 is a .300 AAC Blackout carbine (Great Lakes part no. GL15300BLK) built around a 7075 billet aluminum lower receiver finished in Black Cerakote for a durable, distinctive look. It pairs that receiver with a 4150 chrome-moly-vanadium barrel that’s nitride treated for corrosion resistance and long service life. A 15.125-inch M-LOK style rail keeps the handguard slim while giving shooters plenty of real estate for lights, grips, and other accessories. Feeding from a 30-round magazine, this GLFA carbine gives .300 Blackout shooters a straightforward, well-built platform for both supersonic range work and suppressed subsonic shooting. It’s a solid choice for shooters who want a purpose-built .300 Blackout gun without piecing one together from parts.
