The Energetic Armament Centrix mount system provides reliable retention and consistent alignment. The mount system adds 0.88 (1.17 for the Extended model) from the shoulder of the barrel to the shoulder of the silencer. The Centrix uses the standard 1.37524 thread pattern for compatibility with the Lux and Vox series of silencers in addition to many other manufacturers silencers. The Centrix brake is self-timing and both the brake and mount include wrench flats. The mount uses a stub Acme LH thread to ensure the mount can always be removed from the brake w/o the brake loosening from the host barrel.image
