The primary purpose of the BoreLock mounting collar is to enable the user to continue using a flash hider or a muzzle brake that is already on the weapon.* Designed for use with the Ase Utra BoreLock equipped suppressors. The tapered surface on the BoreLock Collar blocks almost all of the fouling from going into the attachment thread area, enabling easy removal of the suppressor even after several hundred rounds. 

 

The BL-mounting collar is threaded in between the muzzle thread and flash hider. This allows the user to continue using the flash hider of his preference, for example A2 flash hider. To be compatible with the BoreLock mounting collar and suppressors, the muzzle device needs to be under 22 mm in diameter and have a maximum length of 63 mm.

 

NB: With DUAL-S-BL, SL5i, SL6i and SL7i the maximum length of the combination is 52mm.

 

*No flash hider or brake is included with this item.
