The only way to accurately measure and test the length of the chamber of the rifle. Essential when chambering a new barrel to ensure a tight, accurate, safe chamber.

Both Forster and Clymer gauges are made to SAAMI specs.

Brownells USA I used this to check Colt SAA 1st Gen 14/07/2018

1st Gen Colt SAA checked out OK with this gauge. Works as advertised. Had to remove cylinder to get the gauge out, since it would not rotate into recoil plate.
