Product DescriptionThe Breek Arms Sentinel Caged Flash Hider is designed to reduce visible muzzle flash by dispersing and redirecting gases while maintaining a clean, low-profile look. Built for compatibility with the Breek-LOK 3QD quick-detach suppressor attachment system, the Sentinel uses an enclosed (caged) flash hider design to help eliminate snag hazards and increase strength versus open-prong styles. Its black nitride finish on hardened steel provides durability for hard-use environments while supporting a clear sight picture in low-light shooting.Product Highlights Breek-LOK 3QD compatible flash hider for fast, streamlined suppressor mounting setups Enclosed (caged) design helps reduce snagging and avoids the "ring/ping" common to open-prong designs Flash suppression design disperses and redirects gases to preserve night vision and sight picture Black nitride finished 4140 steel construction for strength and corrosion resistance 1/2x28 threads for .223 Remington / 5.56 NATO platformsSpecs Brand: BREEK Model: Sentinel Caged Flash Hider (Breek-LOK 3QD compatible) MPN: BRK4320 UPC: 812296031596 Caliber Compatibility: .223 Remington / 5.56 NATO Thread Pattern: 1/2x28 Material: 4140 steel (nitrided) Finish/Color: Black nitride / Black Overall Length: 2.25 in Weight: 2.0 oz (approx.)
