Who sells mil-spec .303 Field: No bolt disassembly needed?

[Ignition Override]

I've been shooting all five rifles for a while with many reloads of the brass, which could be a good sign

Notice-The advisory at "Yankee Engineers" says "No orders being accepted" for their .074 coin type gauge.

Wanting a mil-spec gauge might still be needed if some of my rifles were to fail the Forster (Saami .070) Field gauge.

No luck on Google-so does anybody else sell the .074 gauge which requires no disassembly of the bolt?

Same idea, Mil Spec coin type.

+1 on the Okie gauges. They are magnetized and stay put on the bolt head while testing. Price is right too.
