Shotgun Combo Gauge
Measure Accurately with the Shotgun Combo Gauge

Accuracy is everything when adjusting your shotgun and the Shotgun Combo Gauge from Robert Louis Co. is as accurate as it gets.

The Shotgun Combo Gauge combines all of the measurements required for proper gun fit, including length of pull, drop at comb and heel, angle of pitch and cast.

Reading both metric and inches for use worldwide, the Shotgun Combo Gauge has easy-to-read bold numbers.

The aircraft aluminum base makes the Combo Gauge incredibly lightweight and easily portable.

Optional dual drop meters are available, as is an optional extension with a magnet. The magnet “glues” the Combo Gauge to gun rib for hands-free operation.
