OPF-G, ACRO is a drop in adapter for superb Aimpoint ACRO sights.
Machined in 4140 steel and black oxide coated, OPF-G, ACRO is a new member of Forward Control’s OPF (Optics Platform, Forward Controls) line. FCD again eschews aluminum for this application and continues to use steel as other OPF plates, they prefer steel plates for steel screws. 4140 steel costs more and takes longer to machine, FCD uses it extensively on other products. Forward Controls does not deem light-weight to be of particular use in this application, but consider reliability and durability far more useful and important qualities.
FCD 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. Forward Controls doesn’t like rebranding but does make exceptions when the products in question are outstanding, and they share the same values as the companies that make them. Forward Controls has 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-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.
