The Burris XTS-135 Speed Dot features a rugged 35mm main tube that is nitrogen filled and sealed to be waterproof and fogproof. A huge field-of-view provides fast target acquisition and the fully coated lenses offer a crisp, clear, non-reflective sight picture. Featuring 11 brightness settings, the SpeedDot is available in either a 3MOA size dot for precision shooting or an 11MOA dot for super-fast action shooting. Each SpeedDot includes Weaver-style mounting rings and an easy-to-find #2032 camera battery with a 200+ hour life at the highest setting.
