Centurion Arms MK11 Ambidextrous 7.62 Billet Receiver Set

Centurion Arms MK11 Ambidextrous 7.62 Billet Receiver Set

Built for strength, precision, and compatibility, the Centurion Arms 7.62 Billet Receiver Set is a premium upgrade for shooters who demand performance and reliability from their large-frame AR platforms. Machined from 7075-T6 aerospace-grade aluminum, both the upper and lower receivers are CNC-cut for exact dimensional accuracy and finished with MIL-A-8625F Type III Class 2 hard anodizing — or Cerakoted per customer request.

Designed to be Knights Armament pattern compatible (Knights/LMT slant cut), this receiver set supports DPMS-pattern barrel extensions and DPMS high-profile handguards, including Centurion’s own 7.62 M-LOK handguards with alignment pin holes. The lower receiver features the largest flared, deep beveled magwell in its class, an integrated trigger guard, and pictograph selector markings for intuitive 90° safety engagement.
