SilencerCo AC2632 ASR Alpha Mount Adapter - Omega 9K/Harvester 300 Black Steel

The SilencerCo AC2632 is the Alpha ASR (Active Spring Retention) mount adapter, a quick-attach and quick-detach interface designed to pair SilencerCo's Omega K-series, Octane 9/45, and Harvester 300 suppressors with any host firearm equipped with an ASR muzzle device.

Precision machined from steel and finished in black, the Alpha ASR provides a repeatable lock-up that allows fast suppressor swaps. It is compatible with all single-port and full-size ASR muzzle devices, including ASR flash hiders, muzzle brakes, and 3-port brakes across the SilencerCo catalog. The mount covers both pistol-caliber cans like the Omega 9K and Nano ASR, as well as the centerfire Harvester 300 rifle suppressor.

Active Spring Retention technology uses spring-loaded locking lugs that hold the mount firmly seated on the muzzle device until the ratcheting collar is released, preventing accidental loosening during fire. Once the collar is unlocked, the suppressor and mount slide cleanly off the host for rapid reconfiguration between rifles and pistols.
