Shims for Accuracy International Barrels

[USNIGHTGUNNER]

These may not even exist, but does anyone manufacture 5/8" barrel shims with an OD greater than .840-.845"? I'm looking for shims that will be a closer match to the OD of my AI 6.5 CM barrel.

I did reach out to the AI crew, but they were all at the range today.

With a little digging, I answered my own question.

You would have to look through their offerings, but TriggerShims makes a lot of different firearm shims, including various barrel shims. You can usually get packs of different thickness and the prices are reasonable and typically include shipping.

To time a muzzle device.

To time a muzzle device.

damn. total thought lapse. i was thinking hes shimming at the chamber end and thats why he was specifying for AI barrels. i mean, damn near any shims will work for muzzle end. id call thunderbeast and see if they have any shims they can provide. last shims i bought were maybe from Operation Parts and were KAC? been a while.

TBAC includes a peel washer with their brakes. Peel washers are effective, but difficult to deal with at times. The OD of the 5/8" peel washer is .840 and the barrel at the muzzle end measures .9815". The 1” shims from McMaster-Carr are a solution for the 5/8 x 24 barrel.

I'm in the process of trying to locate a 3/4” shim with an OD of 1" or slightly less. Desert Tech used to sell them, but none to be found.
If anyone has a source for these let me know.

Sometimes you have to look at shims that are not muzzle device specific, like a shank shim for a 10/22.
