Questions & Answers
Specifications say “Red Dot Sights-Footprint: RMR.” Will it fit securely on a RMR mount plate? Manufacturer Answer

This is an error on the optics planet item specifications, this optic only fit's onto shotguns with a shotgun rib above the barrel such as with over under shotguns. It will not fit the RMR footprint or any other common pistol mounting footprint.

Will it fit a normal ACRO mount? Manufacturer Answer

No it will not, it is made to utilize the included adapter pieces to fit to shotgun ribs only.

Product Info for Aimpoint ACRO S-2 Red Dot Reflex Sight w/ Integrated Shotgun Rib Mount

The Aimpoint Acro S-2 shotgun reflex red dot optic offers a compact design based on the Acro 2nd generation. The optic was designed to mount on ventilated shotgun ribs. The mounting brackets included with sight allow the optic to be utilized on most standard shotguns. Its large 9 MOA red dot simplifies lead visualization, enhancing the automatic refinement of muzzle swing and positioning. The optic is sleek with no protruding features, providing a clear field of view with both eyes open. The low optical axis of 15 mm allows proper gun mounting. The Acro S-2 excels in bird and small game hunting, as well as sporting applications.image
