OuterImpact has gone to great lengths to assure that the fit and finish of this system are top-notch. The Outerimpact M.R.A. for the H&K VP9 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. 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.
