This convenient package of precisely made shims allows for you to securely and precisely align your muzzle device for 1/2 x 28, 5.56mm or .223 muzzle devices on your barrels.

Especially handy for suppressor users who need precision and stability when mounting muzzle devices. Suppressor mounts have to use this alignment set or similar products due to the fact crush washers and peel washers do not delivery the same stability and consitency as shim sets.
