Source for .625 OD Muzzle Shims?

[OldState]

I just acquired a Criterion CORE 13.9” for a Pin and Weld project with a Huxwrks extended FH. I can’t seem to find shims other than .750 OD. These will over hang the barrel and mount. Anyone know where I can find some .625 OD shims?

You try looking through mcmaster carr. They have tons of stuff for the industrial business. Just have to filter down to what you are looking for.

I’ll take a look. I need to figure out how to search for what I need.

I spoke to Precision Armament. They said they would make them if there was enough customer interest

I have several barrels with .625 gas block journals, AFAIK they all use standard shims because the muzzle devices are all pretty standard size. Normal shims are really bigger than that Hux device?

I just searched mcmaster and had trouble getting both dimensions to pull up something.

Try searching arbor, lengthening, and shortening shims. That’s where I found the above option

I’m building with the same the same barrel, likely also a 20” Core. I get the single Arbor shim, thanks for that.

For the lengthening/shortening shims, what would be a good selection?
