    Garden City, Idaho (October 1, 2021) – OuterImpact ® is excited to expand their line of Modular Red Dot Adapters (M.R.A.) to now include a mount for rifles, carbines, and other picatinny topped firearms. The Adjustable Co-Witness M.R.A. features the same mounting pattern of the original M.R.A. but incorporates a riser mount letting the user get a perfect co-witness based on their optic and preference.

    The OuterImpact team had this to say: “Many different optics on the market share mount types but the window size varies greatly. We ran into problems with optics co-witnessing at lower 1/3 or a true cowitness so we made a mount that allowed the shooter to get a perfect viewing window for their sight combinations. The mount has seven different heights and is a two-piece design. The top slides into the bottom and is locked in place via a cross bolt for rock solid mounting.”

    The Adjustable Co-Witness M.R.A. is made of 7075 aluminum, has a black anodize finish, and includes all mounting hardware.
