Well bought myself a new M&P 9L and picked up a Vortex 6MOA Viper Reflex sight. Not impressed. Lock screws don't loc windage and elevation screw totally loose and no moa click to adjust. I am blind LOL so I need the click/feel. So it's on it way back to Vortex for the VIP warranty service ... lets see how that works out. In the meantime I bought a Trijicon RMR Type 2 Adjustable 3.25MOA I am expecting good things. SO I might be having a Vortex Viper Reflex for sale... (When it's fixed) Anyone else have issues with the Vortex Viper??
