Big Chubby Muzzle Brake 5/8-24 Thread, Clamp Style â€œBlackâ€ The Big Chubby muzzle brake is designed to provide the shooter speed and accuracy on successive shots. Curtis Werries, a police sniper, instructor, and competition shooter, developed the Big Chubby so he could recover quickly from recoil, and deliver fast follow up shots. With proper body alignment, shooters have been able to easily hold their reticle on a 2in. circle at 100 yards throughout recoil. This Brake is threaded 5/8â€x24 with .875â€ diameter counter bore. It is designed with an integral clamp that securely holds the brake into place, and allows for a stress free muzzle, the most critical area required for accuracy. It is manufactured at Rat Worx and is made of 4140 chrome moly steel. The finish is a Black Oxide Coating. This brake is designed specifically for 30 caliber bolt action rifles that are built with 5/8 x 24 muzzle threads and .875 barrel diameter behind the threads. This brake fits many factory threaded guns. Please measure your barrel just behind the treads, if you measure .860-.875 you are good. Upon request, this brake may be bored out for 338 cal. and the clamp may be bored out up to .910. We also are able to provide shims for barrels that are smaller than .860â€. Please call us if you have any questions about fit (before ordering) 815-734-7346. Be sure to view our YouTube Videos of the Big Chubby in action. This brake works as advertised!
