20 tactical go gauge

[Geno C]

I’ve decided what to do with my 20 cal barrel. I bought a 20 tactical reamer here and need to know if any other go gauge will work, or if I need to buy the tactical specific gauge. Is a 223 gauge able to be used when chambering or not?

It uses its own Tac 20 gages, not interchangeable with anything else.

Thanks. I was hoping to get away with just measuring short of the 223 gauge, but I guess I’ll rent a gauge for this one.
