EGW Picatinny Rail Gauge

The Picatinny Rail Gauge is manufactured to be a feeler gauge for measuring the specs of your picatinny bases.

The cutout is made .01" bigger so that you can easily see where the picatinny is tight.

With measurements for center (true picatinny spec), min and max, you can gauge if your picatinny is +2 or -2 thousandths.
