Great product - Griffin Armament Griffin Shim Set

Easy to get your muzzle device timed correctly using these shims... The shim kit includes different sizes and plent of them, so I was actually able to use them for 2 rifle... They shipped them to me within a week, so the fast shipping was a plus...the quality of the shims were impressive, and very strong..They do not stand out at all and make the barrels look seamless with the muzzle device.
