Product Overview
This is usually associated with MK12 Barrel Modifications or EC Tuner Brake Modifications
This is a fee associated with me taking the morning to do the programming and run a test piece that will accommodate the suppressor, tuner or muzzle device that doesn't typically mount to a 5/8-24 / 3/4-24 threaded barrel with an OD of .705", .870", .932" but needs to be modified and proofed.
