NOTE: Army issued M17/M18 slide has slightly different plate mounting, the OPF-P320, RMR, RSD is incompatible with Army issued M17/M18.

OPF-P320, RMR, RSD is compatible with P320 X-Five Legion, Legion Carry, and DP Cut.  It is not compatible with P320 Pro Cut, P320 sub compact, AXG, and RX.

Machined in 4140 steel and Melo
nite, OPF-P320, RMR, RSD is a new member of our OPF (Optics Platform, Forward Controls) line.  We again eschew aluminum for this application, and continue to use steel as other OPF plates, we prefer steel plates for steel screws.  4140 steel costs more and takes longer to machine, we use it extensively on other products.  We do not deem light weight to be of particular use in this application, but consider reliability and durability far more useful and important qualities.

OPF-P320, RMR, RSD is a drop in adapter for superb Trijicon RMR sights.  The removal of the P320, commercial version of M17/M18 sight plate cover isn't as straight forward as the Glock MOS, please follow this link for step by step instructions: https://youtu.be/00g-Wpr8tMw

OPF-P320, RMR, RSD has an integrated dovetail for installation of the rear iron sight.  The following sights are compatible:

Truglo P320 backup sights made specifically for Tangodown/FCD plates.  The rear sight dovetail is made for commonly available Glock rear sights, do not use/force a SIG rear sight into the dovetail, doing so will damage the dovetail of the plate.


We will stress the importance of holding the LCI (loaded chamber indicator) with your finger or a piece of tape while removing the plate from the slide, the LCI spring is very small and fragile, and easily damaged.  No need to make this avoidable $5 mistake as we did.

OPF-P320, RMR, RSD is shipped with two 4-40x3/16 Allen screws (plate to slide), a 3/32 Allen key, two T10 5-32x3/8 screws (sight to plate) and a packet of VC-3.

Torque values:
Plate to slide: 6 in·lb
Sight to plate: 9 in·lb

Billet machined in 4140, Melonite coated.

OPF-P320, RMR, RSD is a Forward Controls Design and Tangodown collaboration. Proudly designed and made in the USA.

NOTE:
OPF-P320, RMR, RSD was designed and made for Trijicon's RMR, though Holosun 507c, 508T and 509T (with the adapter plate it comes with) also work on it, we do not guarantee fit and function for these sights on OPF-P320, RMR, RSD.

Army issued M17/M18 slide has slightly different plate mounting, the current OPF-M17/M18, ACRO is incompatible with Army issued M17/M18, AXG, and RX.

OPF-P320, RMR, RSD is compatible with SIG P320 X5 Legion, commercial M17/M18, slides with Romeo1 Pro/DPP cut.

Perfect fit for “off-label” 507C use!
I put this on my P320 factory optic cut slide (with LCI), and then mounted a Holosun 507c with ACSS reticle - the fit was absolutely perfect - precise and zero movement, even without the mounting screws installed. Following the instructions and using the included VC-3 threadlocker, I’ve put roughly 500 rounds through the pistol with no malfunctions or shift in zero - I HIGHLY recommend this mount!

Perfect for Sig M17
Just installed a Trijicon RMR on the Sig 17 using this adapter plate. Super easy install and everything fits perfectly. 10/10 would recommend

Best way to run the RMR on a SIG is to use an M17 or M18 slide and this plate. Fit and finish are perfect and it was easy to install. FCD includes everything you need but the torque wrench. The Truglo sights recommended by FCD are a little lackluster. The front required fitting as is expected for SIG sights. The rear required more fitting than the front which was surprising given it's a Glock dovetail. I would recommend users of this plate consider Dawson .400" front sights for the P320 and .405 rear sights for the Glock dovetail.

507c mount
Ordered this to mount the 507c to my m18. This is a quality plate and probably the best option for mounting a red dot and having back up irons for the m18/m18 platform. Just note that the body of the 507c is taller than the RMR and it slightly obstructs the sight picture with the iron sights made for this plate. The sights are still usable and I would not hesitate to order these again.
