Burris XTR II riflescopes are for the serious tactical shooter. XTR II scopes feature state-of-the-art technology, a 5 times zoom system, and 25% thicker tube construction than the original Burris XTR riflescope. What makes the XTR II ideal for tactical shooters is the high performance optics. The multi-coated lenses optimize resolution, contrast, and low-light performance. The hand-fitted internal assemblies are triple spring-tensioned for absolute shockproofing, even under severe recoil. They are vibration resistant, even on extended vehicular patrols.
