SilencerCo Alpha Direct Thread Mount 1/2×28

SilencerCo Alpha Direct Thread Mount 1/2×28 is a direct-thread mount that allows compatible SilencerCo suppressors to be attached directly to a fixed, threaded rifle barrel. It provides a straightforward method for mounting a suppressor using a 1/2×28 tpi barrel thread.

This mount’s primary purpose is to join a suppressor to a firearm with a matching 1/2×28 thread pitch, reducing overall system length compared with the ASR-style quick-detach mount. It is intended for use on fixed (non-moving/unlocking) rifle barrels; it is not for use on pistols with unlocking or moving barrels, which can damage the suppressor.

• Compatible suppressors: Listed compatibility includes Omega 9 K, Omega 45 K, Octane 9, Octane 45, 45 K, and Harvester 300 (as provided in product information).
