Vermont Gage - 111125300 Steel Go Plug Gage, Tolerance Class ZZ, 0.253 Gage Diameter

I bought 6 of these gages individually to determine the size of locking shoulder I need for an FAL rifle. I bought a Vulcan Arms Locking Shoulder Sizing Rod, but it only goes down to .255. FALs built with DS Arms receivers seem to be notorious for requiring much smaller locking shoulders, and my FAL is one of them.

Perfect size. Delivered promptly.

Perfectly measures exactly as advertised by caliper. I cut it down to the length i needed and it fit exactly in the location it needed to (stop pin for a folding knife)

quality as expected

These are high quality gage pins that are inexpensive considering the level of precision.

This tool as well as others checks primer pockets to see if they are too loose

well satisfied with product& service

Its a gauge pin. Micd right on. All good.

I have several of these, in different sizes, that I use to check gas ports in rifle barrels. Ive checked the pins for size and each one is as advertised.
