Great piece of kit - Trijicon RMR Mounting Kit for Glock MOS and Springfield OSP Models

This is necessary to mount the RMR to the Glock MOS system. Stupid that you need to buy an extra mount when the Glock MOS system is supposed to come with it but it is what it is. The screws for the RMR are too long and the glock MOS kit are too short. This extra mount fits the bill. Some people cut the screws, well go for it if you want but I'll just pay the extra for this. Mounted nicely, use a bit of loctite.
