One thing, besides the the Schott Glass (same stuff in Zeiss), I really liked was the 1:6 ratio for IOR scopes. My 3-18x42 Tactical is an awesome peice of glass. I can crank it down to 3x for walking around and up to any power I feel is capable of completing the task at hand, based upon the mirage.

Just realized the phot's date is wrong. It was about 2 weeks back.

For reference, the gongs are 15" x 25" (20" to top of shoulder)and 10" round from LV Steel.
