Esto es serio, tecnología de última generación para los tiradores competitivos y operadores tácticos.
El visor telescópico de Burris XTR II 8-40x50 cuenta con un sistema de zoom de 5 superior y un 25% de tubo medio más grueso que la construcción de tubo de la anterior serie XTR 
El plano focal en este diseño y todos los visores de gran aumento de la serie  XTR II  permite que el tamaño de la retícula aumente o disminuya según aumente o disminuya el zoom. Compensación de la trayectoria es siempre correcto y proporcional para el ajuste de la potencia seleccionada. Esta retícula es de diseño también llamado primer plano focal o FFP.
Tiene torretas de ajuste de precisión dimensionadas y usa la tecnología de Zero Stop Click.
La óptica de alto rendimiento ofrece lentes Hi-lume®con revestimiento múltiple. Las lentes de optimizar la resolución del objetivo, el contraste y alto rendimiento con poca luz.
Todos los montajes internos están hechos a mano con el triple de resortes tensados-para aguantar el retroceso de los calibres más potentes. Son resistentes a las vibraciones, incluso en patrullas vehiculares prolongadas.

• Designed for serious, technical, long-range precision rifle shooters
• F-Class MOA illuminated front-focal-plane reticle is optimized for long-range, F-Class competitive shooting
• The reticle is laid out in 1/2-MOA increments
• Reticle has a secondary horizontal crosshair and reticle grid to provide 20 MOA of additional adjustment beyond the turret adjustment capability, while still retaining the ability to use the wind hold-off references
• Reticle has 1-MOA and 1/2-MOA marks for wind hold-off
• Front focal plane (FFP) reticle design allows the reticle size to increase or decrease as magnification is increased or decreased; trajectory compensation is always correct and proportional for the selected power setting; also called first focal plane or FFP
• Multi-turn adjustment knobs have a 1/8-MOA adjustment and feature true Zero Click Stop; knobs offer 8 mils per rotation, with multi revolutions of adjustment
• 34 mm body tube
• Excellent resolution optics and tactical-appropriate reticles and adjustment knobs make it easier to identify targets and adjust for windage and elevation
• Versatile 5-times zoom system allows for a larger field of view at close ranges and better target acquisition at long ranges
• Zero Click Stop adjustment knobs let you quickly and easily revert back to the original yardage setting without counting clicks
• Advanced windage and elevation adjustments are fast and easy; accurate and repeatable reticle adjustments match the measurement system of the reticle
• Ergonomic side focus, and easy-to-reach parallax adjustment from 50 yds. to infinity for improved accuracy at long distances
• High-grade optical glass provides excellent brightness and clarity with lasting durability
• Index-matched Hi-Lume® multicoating aids in low-light performance and glare elimination, increasing your success rate
• Illuminated reticle reduces time to get on target in any lighting condition and dramatically increases accuracy when target is dark
• 11 brightness settings (spanning night vision, low light, and daytime), with a convenient battery-saver position between each setting
• Double internal spring-tension system allows the scope to hold zero through shock, recoil, and vibrations
• Waterproof
• Nitrogen-filled body tubes prevent internal fogging in the cold and rain
• Precision-gauged and hand-fitted internal assemblies maintain a consistent point of impact through the magnification range, regardless of shock and vibration
• Solid, 1-piece outer tube is stress-free and durable; withstands shock and vibration from even the heaviest-recoiling caliber
