Black 5/8”x24 Barrel Shim Kit for .308 7.62mm 300BLK .30 Cal (14 Pack)

These are quite good shims. I work on lots of “projects” that require timed muzzle devices. The mic to within a few tenths of the advertised thickness and after doing a couple dozen or so have never had a shim related issue. Muzzles are timed and suppressors are concentric. The black ones blend in nicely with phosphate, nitride, blued and cerakoted tubes. Checks all the boxes I require.

Received 6 separate bags of different size shims within a small box, as advertised. Worked as intended. Like the black color, hard to find elsewhere so paying a bit extra was ok. Quality purchase all around.

High quality, was able to time and shim muzzle device to get it to perfect fit

Great assortment of shims to get my muzzle device timed properly.

This is a set of various size shims for timing a muzzle device on a rifle with 5/8 x 24 threads (most 7.62/308/300 BO barrels). The shims are black and come in bags to show the sizes. There is nothing on the shims themselves to show the sizes. If you have a device that needs to sit at a certain angle on your barrel these will help get you there. There are no included directions. There are videos online of how to do this. Overall not a bad set.

These worked like a charm for indexing a 308 muzzle device

Must have item Top quality item

Nice little shin pack. I would like a higher quantity of each, but you could always just buy multiple packs. They were exactly what I needed to time my muzzle device.
