Area 419 Sidewinder Magnum Self Timing Brake Features The Area 419 Sidewinder Magnum Self Timing Brake uses rearward-facing ports for maximum recoil reduction building on the design of Area 419 s extremely popular Hellfire brake which was independently tested against the best brakes on the market. With one more port than the Hellfire and a larger overall diameter the Sidewinder Magnum delivers a notable increase in recoil abatement for magnum caliber rifles. A proprietary progressive port design increases the size of the first port and decreases it slightly with each subsequent port keeping overall length down without sacrificing efficiency. The brake s face is engraved with the caliber and a horizontal leveling line to make correct orientation simple during installation. Installation uses a universal adapter torqued onto the barrel with a 13/16 inch wrench with the brake and collar assembly then left-hand threaded on until it locks onto the taper and the collar is tightened by hand. This self-timing system means the brake will not turn as it locks and return to zero remains excellent through repeated removal and reinstallation. Made from heat treated 17-4PH stainless steel and finished in black nitride the Sidewinder Magnum is manufactured entirely in the USA on state of the art CNC machines. At 5.6 inches overall length and roughly 7.5 ounces for the brake and adapter together the Area 419 Sidewinder Magnum Self Timing Brake is available for sale at GrabAGun for magnum rifle shooters chasing maximum recoil control.
