BC Case Gauge Ammo Checker, Patrontolk

The single case gauge 9mm/.38 Super/.40 ammo checker lets you verify your ammunition as quickly as possible. 

A Case Gauge is perfect for all competitive shooters to ensure consistency round after round. Utilising a case gauge ammo checker helps avoid misfires, feeding problems, jams, and malfunctions resulting from ammo that is out of spec. 

Drop loaded rounds into the case gauge ammo checker, and if the top of the round sits flush with the top of the checker, you can ensure it will fit in your chamber.

It is manufactured from stainless steel to last a lifetime.
