Trijicon ACOG TA31-CH-G (green crosshair) on BCM 1.93 mount with rear flip cap, RMR mount, OHC killflash, and REM ACOG illuminator - all in pristine condition, bright tritium.  The mount is solid as a rock and gets it as far and low as you can go without a kram and still use a buis and the REM gives you the ability to illuminate with an LED.  No Box  $850 shipped, discreet Zelle or Venmo, PP F/F as last resort.
