Gun Bore (Land) And Groove Air Gages
We offer both bore (land) and groove gages as individual probes or we offer a dual probe that measures both the bore and groove in one pass. This spindle allows the user to measure the rifle bore diameter and groove diameter (lands and grooves) simultaneously, drastically reducing measurement redundancy and work load, as well as less wear and tear on the gage and barrel. The air gage twists in the rifling as you go through the barrel. Our handles are free spinning making it much easier to push the gage through the barrel.
