I got my first USO 3.2-17 ergo w/erek. I have an IOR and USO. I tried a Falcon and that new Weaver tactical mil/mil. I had to send the Weaver back to the factory new out of the box. It was so bad they refunded my money. The Falcon wasn't perfect either but neither did it cost $750 so I kept it for my rimfire. Point is, once you step into the premium glass realm its almost impossible to digress.
