Product Description

The Aim Sports AR5CUB8 Complete Upper Assembly is a fully assembled, ready-to-install upper receiver designed for AR-15 platforms chambered in 5.56x45mm NATO. Built to Mil-Spec standards, this upper features a forged 7075-T6 aluminum receiver with a Type III hard coat anodized finish for exceptional durability and corrosion resistance. The 10.50" barrel is crafted from 4150 Chrome Moly Vanadium (CMV) steel with a black nitride finish, delivering outstanding lubricity and long-term reliability. A full-auto profile bolt carrier group rounds out this high-quality upper, making it an ideal foundation for an AR-15 pistol build or a compact rifle configuration. The 10" free-float M-LOK handguard offers versatile accessory mounting options, while the carbine-length gas system with a low profile gas block ensures smooth cycling performance. Comes complete with a dust cover, forward assist, A2 muzzle brake (1/2x28 threading), and a standard AR-15 charging handle.
