This is a Vari-X III 4.5-14x40mm Mil Dot Tactical, with a 1" tube. I had it mounted on a heavy barreled DPMS AR-15 that I have since sold the upper. I've had this scope for 2 years and it is in great shape. I'm just going to leave the rings and butler creek flip-ups on it for whoever buys it. $450 shipped.
