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

I only buy what I can use.

Seems to be fine.

Measured exactly what it was supposed to.

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.

fantastic plug gauges for what ever project you need them for

Perfect. Great price also.
