Designed, machined and assembled in Greeley Colorado, the Burris XTR III line of riflescopes featuring fresh reticle designs and enhanced field-of-view. Inspired by tactical and competition shooting, precision and reliability are at the core of the XTR III line of optics. Available in a 3.3-18x50mm and 5.5-30x56mm, both models are built with a 34mm body tube for increased strength and extended adjustment range. Elevation adjustments up to 120 MOA on the 3.3-18X50mm will take the 6.5 Creedmoor past one mile. Expanded side parallax adjustment on both models allows fine-tuning focus at shorter distances.The Burris SCR Mil reticle is ideal for precision competition use. With its extended illumination area, you can engage targets at long distances even in low light :1/2-mil holdover lines2/10-mil and 1-mil windage hold-off lines for precision1/10-mil ranging brackets on the crosshairs, at the top, left, and right extremesMil-based, proprietary Burris designSCR stands for special competition reticleExtended center illumination area lets you engage targets at long distances in low light and shadowsFront focal plane design means trajectory compensation and wind hold-off references are accurate at any magnificationIncreases speed and precision for wind hold-off and for range estimation and impact measurement
