Product Description The Area 419 Hellfire Match Self-Timing Muzzle Brake is a precision-engineered evolution of the original Hellfire brake family, purpose-built to deliver elite recoil management for 6mm caliber rifles with 5/8"-24 threads. Unlike conventional multi-port brakes that simply repeat the same port design, this brake features a complete 4-port redesign where each individual port is crafted with a unique length, angle, and height. This deliberate variation optimizes each port&';s function based on the specific pressure and volume of gas acting on it at that position, delivering outstanding recoil reduction, superior muzzle rise control, and zero added sound pressure at the shooter&';s position. Constructed from durable steel with a black nitride finish, it integrates seamlessly with the patented Hellfire Self-Timing system and is compatible with Hellfire Universal Adapters, Suppressor Mounts, Hellfire, Hellfire 2P, and Linear Flash Suppressor accessories. At just 0.60 lbs and 6 inches in overall length, this brake is the new flagship of the Hellfire family without sacrificing the versatility that has made the lineup legendary. Product Highlights Revolutionary 4-Port Design: Each port features a unique length, angle, and height for optimized gas management based on pressure and volume at each specific position.
