Competitive shooters and tactical operators prepare for serious state-of-the-art technology. XTR II riflescopes feature a five-times zoom system, 25% thicker tube construction, dimensionally-matched precision adjustment knobs, and Zero Click Stop technology. Superb, high-performance optics offer Hi-Lume® multi-coated lenses, optimizing target resolution, contrast, and low-light performance. All hand-fitted internal assemblies are triple-spring tensioned for absolute shock-proofing, even under severe recoil, and vibration resistant, even on extended vehicular patrols. True to brand principles, Burris XTR II scopes deliver far more than the modest-for-category price tags, and are protected forever with the Burris Unconditional Forever Warranty.
Dual Focal Plane (DFP) systems separate the center aiming point and crosshairs of the reticle, placing the center in the RFP and the crosshairs in the FFP. This allows the center aiming point to remain a constant size, ensuring the circle and dot is large enough to be effective at low power for close quarter shooting. The crosshairs (which are in the FFP) change size with magnification, meaning the measurements are always correct and proportionate to the target for accurate ranging and trajectory compensation at any magnification. Since the two pieces of the reticle are acting independently, the pieces will overlap slightly at certain magnifications, but this will not prevent the shooter from using the reticle correctly.
