Forward Controls Design OPF Optics Platform for Glock 43X/48 - Trijicon RMR

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, they 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.  They 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, RMR is lightened under the plate.  They don't care for the lightweight mafia and lightening cuts designed solely for show.  A decorated tool is a waste of energy and time.

OPF-G43X/48, 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.

Specifications:

• Torque value:
  • Plate to slide: 15 to 20 in·lbs.
  • Sight to plate: 12-13 in·lbs.
• Weight: 1.21 oz.
• Material: 4140 steel, black nitrided

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.  

Please NOTE:

• A torque wrench is required to properly torque the plate to slide, and sight to plate screws.
• They will soon stop including the L keys with all OPF products, L keys will become optional, they strongly suggest a proper torque wrench to impart the correct torque value.
• 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.  
• For law enforcement and users that require backup sights, Ameriglo GL-527 or their BIS, 43X/48 (made for them 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.
