Description

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.

OPF-G, ACRO produced from late May, 2022 has a slightly widened (by 0.002) recoil lug slot to better accommodate MPS.

OPF-G, ACRO (Optics Platform, Glock, for RMR) is a Glock MOS Adapter Set 01 compatible plate for mounting Aimpoint’s ACRO P1 and P2 on Glock Gen 4 and Gen 5 slides, G17, G19, G34, G35, G41 (width 25mm/1 inch.), and G40.

We like the Glock MOS concept, even if we find the factory MOS adapter plates could use some help. Standards, commonality, availability of parts are all good things. Heretofore, users have had to send in their slides to be milled to accept mini red dot sights, or opt for 3rd party optics ready slides. The time it takes to send in the slides to be milled, and varying quality of the milling work and optics ready slides notwithstanding, there was a lack a standard regarding the sight height, it’d be a coincidence if two slides milled by two different shops share the same sight height. Glock’s MOS may not sit as low as some, but in our opinion, what MOS offers more than makes up for it, namely a uniform sight height, ease of installation, parts commonality and availability.

OPF-G, ACRO is identical to the Tangodown AAM-01. Based on the success of the OPF-G, RMR, we had been asked to develop a Glock MOS compatible plate for the superb Aimpoint ACRO. We saw and tested what our friends at Tangodown has already made, and determined AAM-01 is exactly how we would have done it and there was nothing we could have done better, there is therefore no reason to create another one just like it under our name. 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 AAM-01 and make it OPF-G, ACRO.

OPF-G, ACRO is machined in 4140 steel and Melonite coated. For a short time, OPF-G, ACRO will have both our Cygnus logo, and Tangodown’s logo in tandem.

Proudly designed and made in the USA.

Torque value for plate to slide: 13 in·lb.

Torque value for ACRO P1/P2 mounting screw: 26 in·lb.
