Area 419 Hellfire Self Timing Brake Features The Area 419 Hellfire Self Timing Brake uses rearward facing ports in a proprietary design that controls muzzle rise without relying on top porting directing gas rearward for maximum recoil reduction. Independent side by side testing against some of the best brakes on the market showed the Hellfire achieving 52 percent recoil reduction on a 6.5 Creedmoor test rifle roughly 4 percent better than one of the most popular brakes tested. The brake s self timing collar design means it will not rotate as the shooter torques it down removing the guesswork of where the ports will land once tightened. A universal adapter threads onto the barrel permanently while the brake and collar assembly thread onto that adapter with a left hand thread until snug rotate to level and lock onto a precision taper. Built from heat treated 17-4PH stainless steel the Hellfire is engraved on its face with the caliber and a horizontal line to aid correct orientation and leveling during installation. The brake is sized for bullet calibers up to and including .308 covering popular cartridges like 7mm .284 Winchester and .270 Winchester including magnum variants. At a 1 inch outer diameter for the brake body and 1.1 inch for the collar the assembly adds approximately 2.6 inches to the barrel from the thread shoulder. Manufactured entirely in the USA on CNC machines the Hellfire is finished in Black Nitride and threaded 5/8x24 for direct installation on compatible rifles.
