Centurion Arms MK11 Ambidextrous 7.62 Billet Receiver Set - RAL 8000

The Centurion Arms MK11 Ambidextrous 7.62 Billet Receiver Set (RAL 8000) is built for serious large‑frame AR builders who demand uncompromising strength, precision machining, and premium compatibility. Crafted from aerospace‑grade 7075‑T6 billet aluminum and finished in a rugged MIL‑A‑8625F Type III hard anodize beneath a RAL 8000 Cerakote topcoat, this matched upper and lower set delivers exceptional durability with a refined tactical aesthetic.

The MK11 upper is engineered for seamless integration with Knights Armament and LMT slant‑cut lowers while supporting DPMS‑pattern .308 barrel extensions and high‑profile handguards—giving builders maximum flexibility for precision or duty‑grade configurations. The ambidextrous MK11 lower continues that versatility with support for ambi controls, a deeply flared magwell, and hand‑deburred edges for a premium fit and feel.

Whether you're building a precision SR‑25‑pattern rifle or a hard‑use 7.62 battle platform, this receiver set provides the rock‑solid foundation your build deserves—all proudly made in the USA.
