1/2" x 28 shim kit, for 5.56 muzzle devices only

This shim kit for mounting flash hiders that are to be used as suppressor mounts: Crush washers and split-ring washers can cause canting of any brand of suppressor - replace those crush washers with a precision-made set of GEMTECH shim washers for perfect alignment and timing. Available in 5/8-24 for 7.62 rifles such as AR10-type carbines, or 1/2-28 for most 5.56mm and 6.8 caliber carbines.

    A Must

    Great assortment and something that you absolutely will need if you intend on getting the Flash Hider aligned on your barrel properly. The "one size fits all" shim that comes with a lot of Flash Hiders, 9 out of 10 times won't be the right thickness to get your Flash Hider on your barrel properly aligned.
