AR-9 5.5" Slick Side Spitfire Pistol Upper with Hybrid BCG and Charging Handle - Non-LRBHO

The AR-9 5.5" Slick Side Spitfire Pistol Upper is the perfect choice for building your 9mm AR pistol with enhanced performance and tactical style. This upper features a 5.5" heavy barrel made from 4150 chrome moly vanadium steel, finished in black nitride for durability and corrosion resistance. With a 1:10 twist rate, this barrel delivers excellent accuracy, and it is topped with an AR9mm Spitfire muzzle device with a blast shield to reduce flash and muzzle rise.

Constructed on a 7075-T6 billet aluminum slick side upper receiver, this assembly provides the strength and precision necessary for optimal performance. The non-LRBHO design makes it a sleek option for those looking for a clean, lightweight setup without the bolt hold open feature.

Equipped with a free-floating 4" M-LOK rail handguard, this upper allows for easy attachment of accessories, and the blowback gas system ensures reliable cycling, even during rapid fire. The hybrid AR-9 BCG made from 8620 steel and mag phosphate finish ensures smooth and consistent operation. A Mil-Spec AR-15 charging handle is included for reliable function and ease of use.
