Breek-LOK Compatible Muzzle Devices – TWIN PORT MUZZLE BRAKE

The Breek-LOK QD Suppressor Attachment system stands as the pinnacle of quick detach mounts, offering unmatched speed and simplicity in attachment and detachment. The streamlined muzzle device profile seamlessly integrates with your firearm, enhancing both aesthetics and functionality.

The Breek-LOK Twin Port Muzzle brake was designed to reduce recoil and muzzle rise. This allows the shooter to stay on target and take follow up shots quickly. This is important when speed and accuracy make the difference such as in competitive shooting or self defense situations. The 90 degree and vertical blast vectoring ports mitigate recoil and muzzle rise, countering the force generated through firing. This produces less blowback resulting in higher overall shooter comfort. It features a sleek design that integrates seamlessly with any system, maintaining a clean appearance that looks great on any firearm.

Description of Operation

The Breek-LOK allows a user to quickly affix and remove their suppressor from a firearm. Insert the muzzle device into the HUB with the UNLOCK indicator at the 12 o’clock position, apply downward pressure to compress the spring, and turn the suppressor 90 degrees counter clockwise to lock the lugs into place. The LOCK indicator will now be at the 12 o’clock position. Simply turn the suppressor counter clockwise to ensure the HUB is fully seated to the muzzle device. The user may opt to use two hands to securely seat the suppressor. The detent ring will keep the suppressor from backing off during use.
