I am looking for an Aimpoint Micro or a Holosun 503gu or similar model. I just need a micro RED dot with the external battery access (battery not under mount). I have cash in hand. Let me know what you want for the Aimpoint. I will pay you like new price for Holosun too. I already have a Larue mount, so mount is not a big deal if you dont have one. Thanks!
