This service is for muzzle devices that do not need to be timed during machining such as brakes that can be timed with a shim or locking nut.
Muzzle threads for devices like suppressors and brakes are lathe cut after the barrel is indicated to within .0003" of bore line to ensure proper alignment with the bore. Finished thread tolerances are measured with certified hard chromed ring gauges or a precision thread pitch micrometer to ensure your accessories fit without issue. As standard practice, we fit these types of muzzles with an 11 degree target style crown to reduce carbon buildup on the muzzle face.
