30 mm main tube, side focus , tri - moa reticle . At 16 oz and only 12 1/2", this makes for a good hunting scope. Features typical Leupold glass and build quality . Purchased new from SWFA this winter for $500. I have found that 12 X magnification is not quite enough for 65 year old eyes. Includes original box, paperwork, Leupold life time warranty. Priced at $415 securely packed , insured, and shipped to the conus. Pay-pal f&f or + 3.5% or usps money order. Not interested in any trades of offers at this time. Please deal by pm. Thanks for looking. Herb
