Outerimpact is excited to introduce the Sig® P226 Pistol Red Dot Adapter Mount – M.R.A (Modular Red Dot Adapter).  This product will allow the shooter to utilize a variety of red dot sights on their firearm with one adapter. Outerimpact have gone to great lengths to assure that the fit and finish of this system is top notch. Outerimpact is excited about the increased popularity of the Mini Red Dots on pistol platforms, and not everyone wants to commit to a “custom cut” slide. Custom-cut slides do 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 Sig Sauer P226 answers all the above questions. They have 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. It is well known that shooters do not want to “worry” about losing zero, because of an inferior mount. This is why they provide weaver T-10 Torx screws and steel alignment pins to keep everything aligned and in place.
