Designed for use with the Ase Utra BoreLock equipped suppressors. The tapered surface on the BoreLock muzzle brake blocks almost all of the fouling from going into the attachment thread area, enabling easy removal of the suppressor even after several hundred rounds.


After fitting the forward chamber section is rotated to the correct timing position and locked in place making installation hassle free.


For the Ase Utra BoreLock compatible suppressors see here. 


No licence is required for this item in the UK as it is not designed to diminish noise or flash.
