Mossberg 500 Shotgun - Modular Red Dot Adapter

OuterImpact is excited to introduce the Mossberg 500 Shotgun Red Dot Adapter Mount – M.R.A.  This product will allow the shooter to utilize a variety of red dot sights on their Mossberg with one adapter. We at OuterImpact have gone to great lengths to assure that the fit and finish of this system are top-notch.

We have been excited about the increased popularity of the Mini Red Dots on shotgun platforms. Unfortunately, not all of us are ready or wanting to commit to a “custom-cut” receiver. This does not appeal for various reasons. Some of which are: the price of modification, effects on the resale of the firearm, ability to “try” different Red Dots, etc.

The OuterImpact M.R.A. for the Mossberg 500 answers all the above questions. We precision-machined the adapter plate from 7075 aircraft aluminum. Thus, the M.R.A. plate is extremely durable and lightweight.  As you know, there are violent forces that take place when a gun is fired. We know that shooters do not want to “worry” about losing zero, because of an inferior mount. This is why we utilize weaver T-10 Torx screws and steel alignment pins to keep everything aligned and in place.
