What is the FORWARD CONTROLS DESIGN LLC - OPTIC PLATFORM FOR GLOCK® MOS?

OPF-G, RMR (Optics Platform, Glock, for RMR) is a Glock®MOS Adapter Set 01 and Set 02 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.) and G40 that uses Set 02. Glock's OEM MOS plate's width matches that of the slide, but OPF-G, RMR is already wider to fully support the RMR, thus it is compatible with all MOS equipped Glock®slides. 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. OPF-G, RMR is a collaboration with a USMC combat veteran and former USMC Shooting Team head coach, Tom Shields. We used Glock's MOS adapter plates as a basis, and designed our version of what we think it should and can be. OPF-G, RMR's shape follows its functions, same as all of our products. We outlined the following objectives:

  • Sight is to be fully supported in the front and rear by recoil lugs/fences, with minimum movement.
  • Eliminate the need to use an additional sealer plate.
  • Correct length sight to plate, and plate to slide screws. Screws are to be Torx.
  • Adapter plate is to be machined in steel.

OPF-G, RMR accomplishes all of the goals outlined above. OPF-G, RMR's thickness is unchanged from that of the Glock®MOS plate, it doesn't change the sight's mounted height, nor does it require different iron sights. OPF-RMR is shipped with plate to slide screws (M3-0.5mm x 6mm, same as what Glock®MOS plates uses), and sight to plate screws (6/32 x 3/8), a T10 key and a VC3 packet.

  • Weight: 0.83oz
  • Plate to slide torque value: 13 to 15in/lb
  • Sight to plate torque value: 13in/lb

Proudly designed and made in the USA.

OPF-G For Glock MOS, RMR Footprint
The platform is one of the most rugged I have ever encountered with a forward and rearward fence for the MOS. The M3x0.5 screws are a little small, I would suggest M3.5x0.5 or #5-40 for a more rugged mounting. The Glock slide is quite hard so when machining the flat I suggest a carbide cutter. I worried I would have difficulty tapping the M3x0.5 holes but I was able to locate a M3x0.5 set on Amazon that were just good enough to do the job since Brownells doesn't sell tap sets in that size. All in all I think the customer will satisfied with the professional results of this project.

Optic Didnt Fit
I tried installing this plate, but my RMR wouldnt seat onto the plate. There was still about 1/8 gap at the front where the RMR sits onto the recoil lugs. Called Forward Controls, and they said this was a common problem, which is due to Trijicon not having as tight of tolerances on their machining as forward controls does. I was instructed on where to file their plate in order to get my optic to fit. I know there are plenty of people who love the idea of hand fitting to ensure a very tight tolerance, but thats not what I was looking for. I wanted to get a plate that was sturdy, but one I could simply screw down and forget about. It really doesnt make sense to me for a company to sell a product knowing theyre carrying tighter tolerances than the product it interfaces with. Most importantly though, the idea of possibly needing to hand fit the plate wasnt mentioned anywhere in the description, otherwise I wouldnt have purchased it. If you are someone who wants the absolute tightest fit to your slide and are ok with hand fitting, this is definitely the plate for you. If you want a strong plate that is easy to install, buy a C&H.

Doesn't fit a Glock
I bought this plate to put a Delta Point Pro on a Glock MOS. Had to file it down to make it fit. Which took the finish off exposing the metal to the elements. It was easier to do it myself than mail it back and look for a different plate.
