YHM 5.56 Barrel Shim Set - .5" I.D.

Yankee Hill Machine 5.56 Barrel Shim Kit is designed for correctly and timing a muzzle device for use with suppressors. When running a QD muzzle break and suppressor, you want to use precision machined shims to ensure concentricity between the bore and baffles of a suppressor. Traditional crush washers do not consistently compress when torqued and can lead to baffle strikes with suppressors. This kit comes with multiple different thicknesses to ensure your muzzle brake is perfectly timed to the position you need.

Includes:

• 2x 0.002”
• 3x 0.005”
• 1x 0.020”
