Red Dot Adapter Mount for Sig Sauer® P320 X-5 NOT LEGION Pistols  – M.R.A – Modular Red Dot Adapter

Outerimpact is excited to introduce the Sig® P320 X-5 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 M.R.A. for the Sig®P320 X-5 answers all the above questions. They precision machine the adapter plate from 7075 aircraft aluminum. Thus, the M.R.A. plate is extremely durable and lightweight.
