Features

The IC-A5 300 AAC Blackout 10.5 inch FDE Complete Upper Receiver from LWRC International integrates advanced short-stroke gas piston technology with premium construction for enhanced AR-platform performance. Chambered in 300 AAC Blackout and built around a cold hammer-forged 10.5 inch barrel with a 1:7 twist rate and 1/2x28 threaded muzzle, this upper is engineered to stabilize a broad range of supersonic and subsonic loads while remaining compatible with suppressors and muzzle devices. The mono-forged upper receiver and integrated 9 inch free-float rail create a rigid, continuous platform for optics and accessories.

A low-profile two-position adjustable gas block allows gas regulation for suppressed and unsuppressed use, enhancing reliability across varying configurations. Finished in Flat Dark Earth for added surface protection and a distinctive appearance, the assembly includes iron sights and an ambidextrous charging handle for adaptable operation. Designed for compatibility with AR-15 pattern mil-spec lower receivers, this complete upper offers a refined and durable foundation for custom rifle builds requiring modularity and consistent performance.

Local Law Compliance

Certain firearm parts and accessories, including AR-style upper receivers, are subject to complex and frequently changing federal, state, and local laws and regulations. While an upper receiver may be lawfully sold and shipped as a component, the legality of possessing, assembling, configuring, or using an upper receiver in certain states (e.g., California, Washington State) and localities depends on how it is assembled, combined with other components, and ultimately used. You are solely responsible for ensuring that any assembly, configuration, possession, or use complies with all federal, state, and local laws, including any so-called “assault weapon” bans and short-barreled rifle restrictions.
