ALWAYS ARMED 5" 5.56 NATO GEN 1 IHS UPPER RECEIVER

Build the ultimate ultra-compact AR-15 pistol with the Always Armed 5" 5.56 Gen 1 IHS Upper Receiver. Engineered for extreme maneuverability and close-quarters performance, this complete upper assembly is an ideal foundation for short-barreled rifle (SBR) and truck gun builds.

At its core is a 5-inch 4150 steel barrel featuring a durable salt bath nitride finish for superior wear and corrosion resistance. Chambered in 5.56 NATO with a fast 1:5 twist rate, it provides exceptional bullet stabilization and ballistic efficiency for ultra-short barrel setups. The micro-length gas system delivers reliable cycling, while standard 1/2x28 TPI threads topped with an A2 flash hider allow easy mounting of aftermarket suppressors and muzzle devices.

Forged from heavy-duty 7075-T6 aluminum, the Mil-Spec upper receiver pairs seamlessly with standard AR-15 lower receivers. Encasing the barrel is the 4.25" Gen 1 IHS (Integral Hand Stop) handguard, designed with a built-in safety stop to prevent support-hand slippage near the muzzle. M-LOK mounting slots on three sides, an integrated QD sling attachment point, and a full-length MIL-STD 1913 Picatinny top rail offer endless accessory options.
