Bought this a couple months ago and it's sat in the safe until I mounted it 20 minutes ago to see what I thought. Also have a Trijicon RMR which I like a little more. So I suppose I'm selling this one. If you're going to mount this on a Glock M.O.S. Pistol I've already got the extra screws you need from Vortex to mount the red dot to your adapter plate. Also have other screws for other makes. Anyways looking to get $200. Bought it for $229 + tax and it's brand new with a brand new lithium battery. Check out my other listing as well, open to trades...Maybe a package deal? Thanks for lookin. To our veterans out there, thank you for serving.
