Want use on a rock river pds pistol with Troy micro flip us sights. (W/ RMR) and I’m ready to buy! Will that combination co-Witness?? Thanks, Wayne Expert Answer

You should be able to use the irons through the red dot window, however absolute co-witness will be difficult to achieve since the items are not designed to a set standard height.

Product Info for Kinetic Development Group SIDELOK Low Profile RMR Mount

The KDG RMR Low Profile Sidelok mount allows for the popular Trijicon RMR optic and other brands that share the same mounting base to benefit from KDG Sidelok Technology! The lightweight, 2.4 oz mount pairs with all models of RMR to carry an overall weight of 3.4 oz assembled. Made from high-strength billet 6061 aluminum, the Kinetic Development Group Sidelok mount allows for instant attachment or detachment of the optic to the firearm. This is facilitated with no tools or adjustments, can be accomplished with one hand even while wearing gloves, and with 100% repeatable return to zero! These RMR Low Profile Sidelok Red Dot Sight Mounts are perfect for lightweight firearms and those that swap optics out for different shooting environments. This mount does not offer co-witness with any AR-15 style iron sights but will provide a lower profile setup for those using the mount on shotguns, submachine guns, belt-fed weapon systems, etc.image
