Part Number:OPF-G, RMR
NOTE:
OPF-G, RMR is designed for Trijicon RMR and SRO.  If you use a Holosun and the long set of screws with OPF-G, RMR, you will risk damaging the plate.  We do not support any Holosun sights for use with OPF-G, RMR,

Due to the +/- 0.005 tolerance of RMR and SRO, the plate may need to be fitted in order for the sight to fully seat.  This should not be considered a drop in part.

Trijicon's tolerance between the recoil lugs to the front radiused edge of the RMR is +/- 0.005.  While every OPF-G, RMR has been tested on our RMR and SRO, there is always a chance it might not fit your RMR/SRO without fitting.  OPF-G, RMR's design cradles the sight tightly on the plate between the plate's front and rear fences,  some fitting may be required.  A competent gunsmith can do it easily if you're uncomfortable with fitting the plate to your sight.


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, G45 (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:
1. Sight is to be fully supported in the front and rear by recoil lugs/fences, with minimum movement. 
2. Eliminate the need to use an additional sealer plate.
3. Correct length sight to plate, and plate to slide screws.  Screws are to be Torx.
4. Adapter plate is to be machined in steel.

OPF-G, RMR accomplishes all of the goals outlined above.  Machined in 1018 steel, and black nitrided,  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: 13in/lb
Sight to plate torque value: 13in/lb

Proudly designed and made in the USA.


OPF-G,RMR supports the full width of the RMR and SRO, a sealer plate is not necessary.  Trijicon's position is that if the user is unsure, use the sealer plate, and the plate is so thin, if it is used it doesn't make any difference to the thread engagement.  Trijicon's guide line on whether a sealer plate is required: https://www.trijicon.com/frequently-asked-questions/category/rmr-faqs

OPF-G, RMR is designed to sandwich the sight in its front and rear fence, we make the spacing as close to Trijicon's dimensions and tolerance as we can.  Though we hold a 0.003 tolerance, Trijicon's tolerance is 0.005.  In practical terms, this means while some RMRs will move inside the fences by a very small amount, others will need to be forced into the space. 

Vibra-tite VC-3 is included with OPF-G, RMR.  Instructions can be found here: https://www.vibra-tite.com/wp-content/uploads/213_tds.pdf
Vibra-tite also provides a video on the application of VC-3: https://www.vibra-tite.com/portfolio-items/vc-3-threadmate-overview-video/

A T10 key is provided.  A proper torque wrench in inch/lb increments is required to impart the correct torque to the plate to slide, and sight to plate screws. 

For good printable 8x11"  RMR targets (1MOA dot, 2MOA dot, 6.5MOA dot at 100 yard, 50 yard, 25 yard, and 15 yard), please follow this link: https://www.barelytactical.org/targets/

HOLOSUN COMPATIBILITY:
Trjicon RMR and SRO share the same mounting footprint, OPF-G, RMR is also compatible with SRO.   However, due to the precise fit of the front and rear recoil lugs/fences that are designed to closely sandwich the sight, OPF-G, RMR is not guaranteed to work with all Holosun sights.


As our friend Gary W Thomas II, AIA, NCARB has put it in engineering terms:

To understand the concerns with the Glock OEM MOS plate an explanation of the loads imparted upon the fasteners is required.  When the handgun is fired, the recoil generates a lateral load in the direction of the slide's movement.  This load is transferred through to the fasteners connecting the plate and optic. The Glock OEM plate does not maintain the optic in statis thereby imparting dynamic lateral loads upon the fasteners at the fastener shear plane.  These loads cannot be resisted by the fasteners indefinitely and may result in mounting failure wherein the fastener shears at the shear plane.  

Forward Controls Design's solution is to maintain the optic in a static position relative to the lateral load path by adding fore and aft recoil lugs about the optic.  The front lug resists the dynamic load imparted by the slide inertia during the slide's rearward travel (ejection cycle) while the rear lug resists the dynamic load imparted by the slide inertia during the slide's forward travel (feed cycle). Therefore, OPF-G, RMR  maintains the optic in a static position relative to the fasteners and thereby effectively reduces (if not deletes) the dynamic lateral load imparted upon the fasteners at the fastener shear plane.

Mr
Great plate for the MOS platform. Very well constructed and designed. Light years ahead of anything else out there and far superior. Great CS, fast shipping, nice packaging and informative. Easy to install. Well worth it. And it's made of steel! Makes the MOS gun like a milled gun. Now it's perfection!

Received this in about 3 days. Amazing service. The tolerances are so tight that you may have to use a towel and a rubber mallet to gently tap in the optic to the plate. It gets easier after the first couple times. The sandwich is so tight that without any screws, I can turn the optic upside down and shake it without the optic moving at all. Getting it off can be a pain too, twist and pull up as hard as you can enough to take a non-marring flat to slide under the optic and pull up. Overall, the tolerances are like a milled gun. Will see after 500+ rounds.

Great Upgrade
This product is Fantastic. It’s STEEL!! Fit and finish are top notch. Parts are labeled in separate bags. My RMR is held tight. Same thickness as factory MOS plate. And comes at a fair price. Awesome! Semper Fi

Best plate on the market
Insanely tight tolerates. Without screws the plate will hold upside down on the slide and the SRO/RMR will hold upside down on the plate. Excellent packaging that is well labeled. Custom torch screws that maximize thread engagement. Attention detail on the whole package is outstanding. Additionally, it shipped super fast. Can’t wait for FCD to bring more plate options to the market.

This plate is milled to perfection. I could feel the precision as I slipped it into place. Fits tighter than OJ's glove. I am so glad that I chose this plate over the competitor's.

Incredible Quality and Fit
Great service - I ordered on Black Friday and it arrived Monday USPS - Impressive! Even better was quality and fit in a G19 MOS. There was no sanding, pounding, or adjusting for a perfectly snug fit. I also appreciate the torque specs for the screws and the included thread locker. I'd recommend looking at there other products - Forward Controls has some AR-15 parts I'll be getting in the future.

Mr.
Another awesome package from well trained shipping monkey logistics! After trying every plate made for my G19 mos I can tell you this is the best on the planet. Fits perfect and never moves. Picked up my first on a trade, 6k rounds later still perfect. This is my third one and I won’t carry or own a different plate.

Mr.
Great product. Excellent customer service. Easy to mount to gun and easy to mount optic to plate. Now just need to find the time to re-zero. Thank you Roger for a great product and great customer service.
