Modular Red Dot Mount for H&K USP Pistol

OuterImpact is excited to introduce the Modular Red Dot Mount/Adapter (MRA) for H&K USP Pistol. This product will allow the shooter to utilize a variety of red dot sights on their H&K 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 pistol platforms. Unfortunately, not all of us are ready or wanting to commit to a “custom-cut” slide. 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 Modular Red Dot Mount/Adapter for H&K USP 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.
