Forward Controls Designs has recently rolled out their newest offering the OPF-G,RMR which is the Optics Platform for Glock pattern slides mounting an RMR optic.
Forward Controls Designs states “OPF-G, RMR (Optics Platform, Glock, for RMR) is a Glock MOS Adapter Set 01 compatible plate for mounting Trijicon RMR or SRO on Glock Gen 4 and Gen 5 slides, G17, G19, G34, G35, G41 (width 25mm/1 inch.)
It is incompatible with G40 that uses Set 02.
We like the Glock MOS concept, even if we find the factory MOS adapter plates could use some help.
Standards, commonality, availability of parts are all good things. Heretofore, users have had to send in their slides to be milled to accept mini red dot sights, or opt for 3rd party optics ready slides.
The time it takes to send in the slides to be milled, and varying quality of the milling work and optics ready slides notwithstanding, there was a lack a standard regarding the sight height, it’d be a coincidence if two slides milled by two different shops share the same sight height.
Glock’s MOS may not sit as low as some, but in our opinion, what MOS offers more than makes up for it, namely a uniform sight height, ease of installation, parts commonality and availability.”
