Enhance your compact AR-15 build with the Moriarti Arms 5.56 NATO 6 in Micro Gas QPQ Barrelengineered for shooters demanding extreme maneuverability, superior corrosion resistance, and optimal performance in short-barrel platforms.

Precision-machined from 4150 Chrome Moly Vanadium steel, this barrel features a QPQ (Quench Polish Quench) nitrocarburized surface, offering enhanced strength, reduced friction, and far greater corrosion resistance than traditional chrome lining. QPQ converts the surface at the molecular level without dimensional buildup, resulting in a smoother, harder, and more durable finish.

The micro gas system is optimized for ultra-short AR-15 pistol configurations, delivering reliable cycling when paired with proper tuning. A 1:7 twist stabilizes a wide range of 5.56 projectiles, and the barrel is threaded 1/2x28 for use with standard muzzle devices and suppressor mounts. Outfitted with a QPQ-coated M4 feed ramp extension and an 11-degree target crown, this barrel is built for consistency, durability, and accuracy.

Perfect for PDW builds, ultra-compact AR pistols, and high-performance personal-defense platforms.
