Machined in 4140 steel and black oxide coated, OPF-M17, ACRO, RSD  is a new member of their OPF (Optics Platform, Forward Controls) line.  Forward Controls Design again eschew aluminum for this application, and continue to use steel as other OPF plates, they prefer steel plates for steel screws.  4140 steel costs more and takes longer to machine, they use it extensively on other products.  Forward Controls Design 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-M17, ACRO, RSD is a drop in adapter for superb Aimpoint ACRO sights.  The removal of the P320, M17/M18 sight plate cover isn't as straight forward as the Glock MOS.

Forward Controls Design 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 they did.

Forward Controls Design don't like rebranding, but do make exceptions when the products in question are outstanding, and they share the same values as the companies that make them.  Forward Controls Design've known Tangodown and its folks for a long time, they carry Tangodown products, and are proud to be able to put their logo on the SSM-03 and make it OPF-M17, ACRO RSD.

OPF-M17, ACRO, RSD is precision machined from 4140 steel, and QPQ coated.  Aimpoint ACRO P1/P2 requires the plates to adhere to Aimpoint ACRO TDP with tight tolerances, OPF-M17, ACRO, RSD has proven to be the best choice among professional users.

OPF-M17-ACRO, RSD is shipped with two M4 0.7mm x 6mm  (torque value: 20 in·lb) and a packet of VC-3.

Proudly designed and made in the USA.

Please NOTE:

• OPF-M17, ACRO, RSD is compatible with MIL issued M17/M18, it only works with the civilian version of M17/M18.

• It is not compatible with P320 Pro Cut, P320 sub compact, X Carry, AXG, Spectre Comp, and RX, P320 Max, P320 Grayguns.
• 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.
• Steiner MPS users: MPS's recoil lug underneath the sight may vary in width and be slightly wider than that of the ACRO.  Should this be the case, firmly push the MPS on the plate, or gently tap on the sight until the MPS fully seats.
• OPF-M17, ACRO, RSD is only guaranteed to work with Aimpoint ACRO P1 and P2, and Steiner's MPS.  Forward Controls Design have not tested it with the cheap Chicom sights under different guises from various companies that purportedly use the ACRO footprint.  Forward Controls Design neither endorse, nor support their use on OPF-M17, ACRO, RSD.  For defense and duty, they also do not recommend P2 copies.
