Forward Controls Design Sig Sauer M17/M18 Acro Plate – Rear Sight Dovetail

NOTE: Army issued M17/M18 slide has slightly different plate mounting, the current OPF-M17/M18, ACRO is incompatible with Army issued M17/M18, but a universal version compatible with both military issued, and civilian, commercial version is coming in 2021).

Machined in 4140 steel and black oxide coated, OPF-G, ACRO, 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-G, 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, please follow this link for step by step instructions: https://youtu.be/00g-Wpr8tMw

Trijicon Bright and Tough’ Suppressor Sight Se

Part number: 600907

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.

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, RSD 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.
