Accubrake™
All Weatherby® rifles are available with our special Accubrake™ option (standard on .30-378, .338-378, .378, .416 and .460 models). By adding an Accubrake™ to your rifle you can significantly reduce felt recoil...up to 53 percent. That’s nearly 10 percent more effective than our nearest competitor.
Available for four different barrel diameters, with checkered thread protector, for a near perfect brake-to-barrel contour match. Because the crown is located at the end of the barrel, not the brake, the lands are protected, preserving accuracy. As the bullet exits the barrel it passes through the brake without contact. The brake in no way adversely affects velocity or accuracy, only felt recoil and muzzle jump. Constructed of stress-proof steel alloy or 420 Series stainless steel and are available in high polish or matte blue finish or matte stainless steel.
To preserve accuracy and safety, an Accubrake™ should only be installed by Weatherby, Inc. or by an Authorized Weatherby® Service Center. For more Information, contact Weatherby® at (805) 227-2600, or visit an Authorized Weatherby® Service Center.
