Instructor Shotgun Sight
When selecting the size of the Instructor sight it is best to measure the width of the rib for a precise fit however if the shotgun is not at hand the following can serve as a guide.
5/16" width fits Remington field models such as the 870s and 1100 12 guages Benelli 12 guages Many other 12 guage shotguns use this width.
3/8" width fits the Remington SP10 10 guage and many other wider rib width shotguns
1/4" width fits narrow width ribs common to 28 guage and 410 guage Baretta field models. Browning Citori
6mm fits the Browning gold 20 guage and other narrow ribbed guns
There are many shotgun ribs that are tapered both in height and width so please be aware of this when measuring the ribs. If the rib is of very low height at the distal end the magnets may not contact the metal and of course thereby not adhere well to the rib.
