I have a like new, Burris Fastfire 3, 3moa red dot sight. I had this on a Mark III 22/45, but I sold the gun and the buyer did not want it. It includes everything it came with including the mount for a scope rail. I'll sell it in like new condition for $125 or best reasonable offer. Cash only. I can also throw in a scope rail for a Ruger Mark series pistol if you want it. Prefer face to face transaction in Waco. Call or text Mike at (512) 8four4-o434
