1 excellent condition GG&G Aimpoint Low Mount for sale. This can be used like the other post for that RASII hump. Includes built in spare battery compartment that also doubles as a replacement battery cover for the CompM-XD's.
This is an extra that I had on one of my AR's (sold the AR) and at $80 shipped MO or Paypal (+3%) accepted this is half of what it sells for.
Make offer if not in range.
