Talley RMR Mount Features Fully CNC machined from 6000 series aluminum alloy this mount is hard-coat anodized to 65 Rockwell hardness a finish process that ensures the mount s craftsmanship holds up across the working lifetime of the shotgun it s installed on. Because the plate is cut directly to an RMR footprint shooters can mount their red dot straight to the receiver without adding the height or bulk of a full-length Picatinny rail keeping the sight picture low and the overall profile trim. Precision CNC manufacturing to tight tolerances means the mount fits its specified Winchester Super X models without the play or wobble a loosely toleranced part would introduce. The mount uses only the two rearward-most mounting holes on the receiver positioning the red dot exactly where it needs to be for proper eye relief and sight picture on a shotgun. All mounting screws and the installation wrench ship in the box so shooters have everything needed for a complete install without sourcing separate hardware. Whether upgrading a dedicated turkey gun for faster target acquisition in thick cover or converting a tactical Super X for defensive use this mount gives Winchester SX2 SX3 and SX4 owners a lightweight minimized solution for running RMR-footprint red dot optics.
