LWRC IC-PSD ICMKII 5.56 NATO 8" Patriot Brown Upper Receiver

The LWRCI IC‑PSD/ICMKII A5 Patriot Brown 8″ Upper is a high‑quality short‑barrel AR‑pattern upper receiver assembly built on LWRC International’s proprietary short‑stroke gas‑piston system, engineered for reliability and smooth operation in compact configurations. Chambered for 5.56 NATO and finished in Patriot Brown Cerakote for rugged corrosion resistance and distinct styling, it includes a cold‑hammer‑forged barrel with an 8″ (nominal) profile and 1:7″ twist optimized for consistency in short‑barrel use. The upper incorporates a free‑float modular rail system, LWRCI Skirmish backup iron sights, and an ambidextrous charging handle, and is designed to mate with any standard AR‑15 mil‑spec lower to complete a custom build that balances compact handling with premium LWRCI build quality and piston reliability.
