Gun Barrel Bore Gauge

BG10 product image


The BG10 Gun Barrel Bore Gauge System is highly recommended for applications where measurement accuracy must not be compromised by the priority for a fast operational turn-around time.


The BG10 Gun Barrel Bore Gauge System is an electro-mechanical measuring device that was originally introduced into service by the RAF for the high-speed measurement of aircraft cannons, to ensure minimum operational aircraft turnaround time. Measurements are taken at 16 pre-determined positions along each bore, which are then compared to pre-stored warning and rejection criteria. The actual measurements taken are displayed to the Operator on an LCD display and the measurements stored for future reference. The system will automatically provide a visual indication on the Hand Held Unit whether the barrel was acceptable, close to tolerance or rejected – all this to be undertaken in less than five minutes!

The BG10 System is provided in a rugged carrying case affording protection, storage and ease of transportation.
