$54.99
The Breek BRK4324 Sentinel Caged Flash Hider is a 9mm flash hider purpose-built for shooters running the Breek-LOK 3QD quick-detach suppressor system. If you're tired of muzzle flash washing out your sight picture in low-light hunting or tactical scenarios, this caged design works by dispersing and redirecting combustion gases away from your line of sight—keeping your vision sharp when it counts. The closed-cage design also eliminates the snagging and vibration ring that open-prong flash hiders are notorious for, giving you a more refined shooter's experience whether you're on the range or in the field.
Built from 4140 hardened steel and finished in durable black nitride, the Sentinel is engineered to handle the rigors of regular shooting and suppressor attachment cycles. The internal threading is reinforced to outlast standard flash hider designs, and the low-profile 2.25-inch length keeps your setup looking clean and balanced without unnecessary bulk. A peel washer is included to ensure a solid, repeatable fit on your 5/8"x24 threaded barrel.
This is a true American-made component—designed and manufactured stateside—that plays nicely with any Breek-LOK 3QD–equipped suppressor. If you're already invested in that quick-detach ecosystem, the Sentinel gives you the flash reduction you need without compromising the speed or simplicity of your setup.
