The LWRC ICDI Direct Impingement .350 Legend 16" Complete Upper Receiver is a premium AR‑style upper designed to bring .350 Legend performance to a direct‑impingement platform with LWRC’s hallmark engineering and build quality. Built around a 16‑inch NiCorr‑treated cold‑hammer‑forged steel barrel with a 1:16" twist and **9/16×24 threaded muzzle, this upper is optimized for the .350 Legend cartridge, offering excellent accuracy and reliability for hunting and tactical applications. The complete upper features LWRC’s proprietary keyless bolt carrier design and a monoforged upper receiver with an integrated rail base, providing a rigid free‑float platform for enhanced precision and accessory mounting. A full‑length Picatinny top rail and M‑LOK slots allow for easy attachment of optics, lights, and other gear. Finished in a durable black hard‑anodized surface, the upper delivers both rugged durability and refined aesthetics, and is engineered to interface seamlessly with a MIL‑SPEC AR‑15 lower, making it a versatile upgrade for shooters seeking modern performance in a straight‑wall‑cartridge build.
