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 brakes. They allow for the neccesary adjustments and a stable and parallel surface when mounting a 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
