REXUS UltraShims Muzzle Device Timing Kit

Description

Time your 5/8-24 muzzle device with our REXUS UltraShims Kit, which includes 2 each of 5 thicknesses of stainless steel shim washers for 10 total. Shims have a .742 outside diameter that mates perfectly with our line of UltraSlim muzzle devices to allow a .750 gas block to slide on and off. The thinnest, .002, accounts for roughly 17° of muzzle device rotation, the .003 for 26° rotation, the .004 for 34.5°, .008 (69°), and .016 (138°).

By mixing and matching, one can fine-tune timing in .001 increments. REXUSUltraShims provide device timing while allowing maximum thread engagement, unlike thicker systems. Further, UltraShims are infinitely reusable, for those who want to uninstall their muzzle device for cleaning. Finally, unlike crush washers, UltraShims do not introduce misalignment.
