A precision tool to clean-up dinged muzzles on the Garand. The PTG M1 Garand Crowning Tool and Muzzle Radius Cutter is built to the original M1 Garand (Pre 1964) specifications so the muzzle and crown are perfectly profiled to original. Removable pilot design allows for accurate use with a T-handle or a lathe. Made from M42 steel for years of precision cutting. Will work on any 30 caliber barrel. Includes one 30 caliber bore bushing.
The Pre-64 model features a radiused crown similar to the military specification "V" shaped crown for the M1 Rifle
The 1964 Pattern features a triple angle crown and is for models manufactured in 1964 and after.
