Plug Gauges for Forcing Cones in Revolver Barrels
$6.00
By simply slipping the Plug Gauge into the barrel throat, it’s possible to tell at a glance when you are approaching the correct diameter. Warns you before you go too far. Also valuable as a diagnostic tool for guns brought in with accuracy complaints, (designed for chamfers cut with our tools – may not give a correct reading on guns with other degrees of chamfer). Each gauge is self-piloted, precision-ground, hardened and stepped to show minimum and maximum optimum diameters. 11° and 18° Gauge measures both chamfer angles.
