Area 419 Hellfire Features The Area 419 Hellfire Self Timing Brake uses rearward facing ports for the ultimate in recoil reduction a proprietary design that controls muzzle rise without relying on top porting. Independent testing on a 6.5 Creedmoor rifle showed a 52 percent recoil reduction roughly 4 percent better than one of the most popular brakes on the market. Installation is simple because the universal adapter torques onto the barrel with a 5/8 inch wrench and never has to come off while the brake and collar assembly left hand threads onto the adapter and locks into place without tools. The face of the brake is engraved with the caliber and a leveling line making correct orientation obvious at a glance. Machined from heat treated 17-4PH stainless steel and finished in black nitride the Hellfire is built to handle any bullet caliber up to and including .308 covering 7mm .284 .270 and magnum rounds. The brake measures 6 inches overall with a 1 inch outside diameter and a 1.1 inch collar diameter adding about 2 inches to the barrel s overall length. Because the self timing design will not rotate as the collar is torqued shooters get excellent return to zero when removing and reinstalling the brake for cleaning or suppressor use. Manufactured entirely in the USA on CNC machines the Hellfire brake is built for precision rifle shooters who demand consistency shot after shot.
