OUR GO TO BRAND FOR OPTIC MOUNTING PLATES
ATTENTION, 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.
For the new M17/M18 and SIG P320 with the Delta Point Pro cut, Forward Controls offers the OPF-G, ACRO, RSD (rear sight dovetail).
OPF-M17, ACRO, RSD is compatible with MIL issued M17/M18.
Machined in 4140 steel and black oxide coated, OPF-G, ACRO 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-G, ACRO 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, please follow this link for step by step instructions:

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.
OPF-M17, ACRO is identical to the Tangodown SSM-01, ACRO. We don't like rebranding, but do make exceptions when the products in question are outstanding, and we share the same values as the companies that make them. We've known Tangodown and its folks for a long time, we carry Tangodown products, and are proud to be able to put our logo on the SSM-01, ACRO and make it OPF-M17, ACRO.
OPF-G-ACRO is shipped with two 3/32 Allen screws (torque value: 12 to 14 in·lb), a 3/32 Allen key, and a packet of VC-3.
Proudly designed and made in the USA.
