ALWAYS ARMED 5.5" 9MM GEN 1 IHS UPPER RECEIVER

Engineered for close-quarters reliability and maximum maneuverability, the Always Armed 5.5" 9mm Gen 1 IHS Upper Receiver delivers top-tier performance for compact Pistol Caliber Carbine (PCC) builds. Perfect for custom AR-9 pistols and truck gun setups, this upper offers an ideal blend of durable construction and tactical utility.

At the core of this assembly is a 5.5-inch 4150 steel barrel finished in black salt bath nitride for superior corrosion resistance and extended barrel life. Chambered in 9mm with a versatile 1:10 twist rate, it delivers consistent bullet stabilization and match-grade accuracy across standard target and self-defense factory loads. The muzzle features standard 1/2x36 threading topped with an A2 flash hider, making suppressor and muzzle device integration fast and seamless.

Forged from ultra-tough 7075-T6 aluminum, the Mil-Spec upper receiver easily installs on standard AR-9 lower receivers accepting Glock or Colt pattern magazines. The barrel is wrapped in a 4.25" Gen 1 IHS (Integral Hand Stop) handguard, designed with a built-in safety stop to prevent support-hand slippage on short barrel setups. M-LOK attachment slots on three sides and a full-length MIL-STD 1913 Picatinny top rail offer endless options for mounting red dots, tactical lights, and lasers.
