Bolt action rifle muzzle brake installation: Installing a Surefire MB762SSAL/RE
We decided to add a Surefire muzzle brake to our custom 308 Remington 700 lightweight tactical rifle we built in a previous article. The Surefire MB762SSAL/RE muzzle brake provides excellent reduction in muzzle flip as well as the ability to mount one of their suppressors. The design of the brake requires that 2.15″ of the barrel behind the threads to be no more then .775″ in diameter to fit under the device. For many bolt action rifles, this requires that the muzzle be turned down behind the threads.
We ensure our rifle is safe and empty and removed the barrel from the action. The following documents the process we used to install our brake and is intended for information purposes only.
NOTE: On this installation we did not cut the threads on the lathe- which would have been a better method. Instead, we used the die and tail stock method. This was done to show various methods one can use to accomplish the same results. Current best practices would suggest single pointing the threads on the lathe.
