The Burris XTR II 5-25X50 201056 was designed with a 25% thicker tube than the original XTR. The lower magnification ranges have a wide field of view for easy scanning, while the higher magnification ranges are great for long-range shots. The Burris XTR II 5-25X50 features an illuminated SCR MIL reticle with 11 illuminated brightness settings that span night vision, low light, and daytime settings with a battery-saver position between each setting.
