Burris 200934 Matte Black Black Diamond Riflescope/Ballistic Mil Dot Reticle/Side Focus Making a shot on a ram at 400 yards or a coyote in the next zip code requires a unique skill set and special tools. Beyond superior vision, patience, a steady hand, and an accurate rifle, shooting ultra-long-range is all about having the right scope. A scope like a Burris Black Diamond. Engineered specifically for the rigors of long range shooting, Burris started with a 30mm tube then added multi-coated optics precision-ground from superior glass. The end product is a scope that delivers extraordinary sharpness, contrast and clarity that out-shines even high dollar European scopes. Burris has kept the Black Diamond's length, weight, and mounting profile to a minumum. Other practical features like fingertip adjustable and resettable dials, up to 4 inches of eye relief, and convenient side parallax adjustments are a big plus when the pressure is on.
