The Area 419 Hellfire 2P Self-Timing Muzzle Brake is engineered for 223 Remington and compatible with bullet calibers up to and including 0.243 (6mm)—covering 223, 5.56 NATO, 204, and 17 caliber applications. Designed for semi-automatic and hunting weapons systems with barrels of 20″ or less, this brake delivers optimized performance while prioritizing shooter comfort.
Part of the Patent Pending Hellfire Modular Brake System, the Area 419 Hellfire Self Timing Brake was engineered from the ground up to be extremely effective, easier to install, and more versatile than existing self-timing brake designs. Two caliber selections simplify your choice while minimizing any efficiency difference between caliber-specific brake bores and the next size up, keeping costs down without sacrificing performance.
Installation is straightforward: torque the universal adapter onto your barrel using a 5/8″ wrench—this piece stays permanently installed. LEFT HAND thread the brake and collar assembly onto the adapter until nearly snug. Rotate the brake until level, push it into the adapter until it locks onto the taper, then hand-tighten the collar fully. The brake will not turn as you torque the collar, eliminating guesswork about port alignment. A simple round knurled nut requires no tools to time the brake, and return to zero is excellent—removal and reinstallation require no zero adjustment.
