the only shim kit that works AND looks right!

surefire actually did some R&D before manufacturing & supplying this product, unlike their competitors. these shims have an outside dimension smaller than a standard .750 barrel so that the muzzle device & barrel are streamlined, aesthetically nice. i can’t tell you how many companies like YHM have this .875 or ,9 OD and the shims protrude much farther than the barrel & muzzle - it looks ugly & shade tree - as in just unacceptable. but surefire got it right on their muzzle timing kit. i have these shims on a wylde barrel & epsilon vg6 slim; the shims are smaller than the epsilon but ID big enough to slide over barrel threads without fuss. never thought i’d be so impressed with measley shims but it’s far & few between in the market. i will be buying the item in 5/8x24 as well
perfect product, small OD matches barrel

i bought this kit to time a vg6 muzzle device on a 223/556 cal. i was so impressed how surefire got it right out of so many others that have failed. you will find that the washers have the same outside diameter as the barrel & muzzle devices, even slim examples such as the epsilon 556. the ID is just large enough to slide over the threads with ease. i didn’t even use the thread locker yet since i’m still going back & forth with muzzles but things don’t come loose on a 556 like they do on 762. anyway, i was pretty happy that the dimensions matched up with the barrel and the various thicknesses allowed me to PERFECTLY time my MDs
