5/8" x 24 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.

    Perfect Fix

    Posted by Dan Hoban on Jul 22nd 2019

    Purchased these to help time a muzzle break form Dead Air. the ones from Dead air I had a hard time getting the correct alignment, and when it was close the shims diameter are too large to get a wrench on the flats. These shims worked perfectly .

    Just what I needed at a great price!

    These shims were perfect for mounting and timing all my rifles’ muzzle brakes. Timing was easy and comes with quite a few shims - I had enough left over from each pack to shim another rifle if needed. (I bought 2 packs of 1/2 x 28 and 2 packs of 5/8 x 24).

    Bravo Company prices can’t be beat and as usual, shipping was quick and arrived with extra merch packed in with my order! Nice touch which is always appreciated.

    Top notch all round!

    7.62 Shims

    Posted by Jordan on Apr 10th 2019

    I received my shims today, 03/22/19, and I am very happy with them. I have BCM’s 9” 300 Blackout MCMR upper and I use a Dead Air flash hider. The shims that come with the DA muzzle devices are way too large when it comes to outer diameter and stuck out past the shoulder on the blackout barrel due to the unique profile. These shims cleaned everything up and fit wonderfully.
