Breek Arms Sentinel Caged Flash Hider 30 Cal 5/8x24 Black Nitride

The Breek Arms Sentinel Caged Flash Hider is a purpose-built muzzle device machined from 4140 hardened steel with a corrosion-resistant black nitride finish. Designed for .30 caliber rifle platforms, the caged design captures and redirects propellant gases to dramatically reduce muzzle flash, preserving shooter visibility in low-light conditions.

Cut with 5/8"x24 TPI threads, the Sentinel installs on any .308 Winchester, 7.62, or 300 Blackout barrel with the matching thread pitch. It is engineered specifically for use with Breek Arms' Breek-LOK 3QD quick-detach suppressor mounting system, providing a secure and repeatable lockup when paired with a compatible 3QD hub. This makes the Sentinel an ideal host muzzle device for shooters who run a Breek-LOK-equipped suppressor.

The Sentinel measures 2.25 inches in overall length and weighs approximately 2.0 ounces, adding minimal weight to the host rifle. Installation is straightforward using the included peel washer, with Breek Arms specifying a torque of 20-30 ft lbs for proper fitment.
