Product Info for Breek Arms Breek-LOK Solo 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.image

The Breek-LOK Solo 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. The short profile makes it a great option for SBR or pistol caliber carbines.
