The Burris 6x-24x-50mm XTR Xtreme Tactical Riflescope has been engineered as the ultimate in high performance optics. The Burris Riflescope has extra large ultra-premium lenses which can produce unsurpassed resolution, clarity and brightness. The riflescope by Burris is also enhanced with a new StormCoat that can cause water to bead and shed off for a clearer view when water drops are present. The outer tube walls are 25 percent thicker for 42 percent greater strength while a double-force coil spring suspension locks the inner tube in place for unfailing accuracy.
