NOTE: OPF-G43X/48, RMR is designed for and only compatible with GLOCK G43x and G48, and Trijicon's RMR, SRO, RMR HD and RCR. It will not work with other GLOCK models, and other red dot sights.
If you're looking for an RMRcc plate for G43X/G48, OPF-G43X/48, RMRcc is made for RMRcc, can be found here: OPF-G43x/48, RMRcc
For law enforcement and users that require backup sights, Ameriglo GL-527 or our BIS, 43X/48 (made for us by Ameriglo with a front sight height 0.450", rear sight height 0.554" will be needed for lower 1/3 co-witness. GL-808 is slightly taller and also suitable, GL-808's taller sights are required for RMR HD and RCR.
OPF-G43x/48, RMR (Optics Platform, Forward Controls, G43x/48, RMR) is the latest member of the OPF line. G43x and G48 MOS slides are designed for direct mounting of the Shield RMSc sight. Trijicon's RMR is longer and wider, and requires an adapter plate which also necessarily raises the mounting surface in order to mount an RMR.
With the OPF-G43x/48, RMR, we didn't merely raise the mounting surface to provide a platform for the RMR. As RMR is longer than the G43X/48 MOS cut, the sight overhangs on the slide. We provide not only lugs, but also a front recoil fence that together with the recoil lugs, holds the sight immobile before the sight to plate screws are installed and torqued to specified value of 12 to 13 in/lb.
OPF-G43X/48 ships with 2 plate to slide screws (M4-0.7mmx10mm), 4 sight to plate screws (T15 6-32x3/8 ), and a packet of VC-3.
OPF-G43X/48, RMR is lightened under the plate. We don't care for the lightweight mafia and lightening cuts designed solely for show. A decorated tool is a waste of energy and time.
RMR has a huge lightening cut, but it's invisible when the plate is
installed and in use. There's a vast (relatively speaking) area under the plate
that doesn't do anything except taking up weight, so it's removed.
A torque wrench is required to properly torque the plate to slide, and sight to plate screws.
Plate to slide: 15 to 20 in·lbs.
Sight to plate: 12-13 in·lbs..
Material: 4140 steel, black nitrided
For lower 1/3 co-witness, we recommend sight sets with at least 0.450" front, and 0.544" rear, the tip of the sights are low in the RMR's window, such as BIS, 43x/48
Note that BIS, 43X/48 are not tall enough for RMR HD and RCR.
GL-808 (0.500" front sight) is taller and also compatible, GL-808 is necessary for RMR HD and RCR.
We have collaborated with the wonderful folks at Ameriglo, and they have produced a version of GL-527 for us: BIS, G43x/48 https://www.forwardcontrolsdesign.com/buis-g43x48.html
BUIS, 43x/48 is available with or without a front tritium dot, we suggest the all black BIS-43X/48 (without the tritium), as RMR is slightly elevated on OPF-G43x/48, RMR, the tritium dot is partially obscured on the bottom.
We will soon stop including the L keys with all OPF products, L keys will become optional, we strongly suggest a proper torque wrench to impart the correct torque value.
