Shim Kit -- AR-15 Muzzle Brake, 1/2" Thread

Shim Kit (PN 10.001) for AR-15 muzzle brakes, 1/2" Thread

These shims are “Made in USA” and the best we could find to complement our muzzle brake PN 04.107. They allow for an adjustable, stable and parallel mounting of the muzzle brake.

Originally for a 1/2" - 28 thread, this kit allows for a wide range of adjustability with the variety of shim thicknesses contained, to mount and correctly orient a muzzle break with a 1/2” – 36 thread.
The 2mm shim is well suited to bridge the non-threaded portion of a muzzle thread if there is no thread relief cut.

The kit contains shims of the following thickness, each with a bore diameter of 12,9mm and an outer diameter of 17,7mm:

• 4 pcs. 0,075mm
• 3 pcs. 0,11mm
• 3 pcs. 0,22mm
• 2 pcs. 0,34mm
• 1 pc. 2mm
