Forward Controls Design has expanded its OPF family of optics plates with the OPF-G43x/48 RMR. The plate allows a full-sized RMR, SRO, or RCE to be mounted to a Glock 43X MOS or Glock 48. The company decided to make this option available for users who prefer the larger window size of the RMR.
The OPF-G43x/48, RMR raises 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. To secure the optic in place, the company provides lugs and a front recoil fence. With those in place, the sight is immobile before the sight-to-plate screws are installed and torqued to a specified value of 12 to 13 in/lb.
As to the quality of the lugs, the company has this to say: “All our RMR OPF plates have recoil lugs that meet specifications and are never undersized. These recoil lugs are essential to prevent mounting failures, as using screws alone as recoil lugs with the RMR footprint is insufficient. We are proud to say that this design has had no failures throughout the lifespan of the product family, knowing that users can trust it.”
Another bonus here is that the OPF-G43x/48 RMR is lightweight at 1.21 oz. A large lightening cut, which is hidden upon installation, helps reduce the weight.
The package includes two plate-to-plate slide screws, four sight-to-plate screws, and a packet of VC-3 Vibra-Tite.
Optic Plate Design
FCD’s plates focus on three criteria: a design that holds optics securely, tight tolerances, and strong material selection. These criteria are essential for LE and MIL applications. FCD supports factory-milled slides, providing a standardized mounting solution for a wide range of optics. FCD uses US-sourced 4140 steel and machine shops with tight tolerances. OPF optics plates ensure secure mounting that maintains zero during drops, one-hand manipulations, and battery changes (RMR).
Forward Controls Design has been supplying OPF-G, RMR plates to LE, MIL, and civilian customers since March of 2020. All of their products are designed and manufactured in the USA.
