Adjustable Co-Witnessing Modular Red Dot Optics Mount for AR Platforms

OuterImpact is excited to introduce our Adjustable Modular Red Dot Optics Mount for AR Platforms. This product will allow the shooter to utilize a variety of red dot sights and optics on any rifle that has a picatinny rail, as well as allowing the shooter to dictate the height of optic or level of co-witness they prefer, from absolute to lower third and multiple points in between. Using the tops available (sold separately), it is compatible with all of the Red Dots our current M.R.A. adapters accommodate (31), the optics using the Aimpoint Micro Standard (38), and also the Trijicon MRO Standard (3) footprints. The mount only takes a couple of minutes to install on any Picatinny Rail type. Once zeroed, you can freely adjust the level of the mount and no re-zeroing is required. See the mount in action on Rumble.

We at OuterImpact have gone to great lengths to assure that the fit and finish of the Adjustable Modular Red Dot Adapter for AR Platforms is top-notch. We precision-machine our adapter system from 7075 billet aircraft aluminum and all mounting hardware is included in the kit.
