The XTR II 1-5x24 mm riflescope features a 5-times zoom system and 25% thicker tube construction than the original XTR Riflescope. It has dimensionally-matched precision adjustment knobs and Zero Click Stop technology. High-performance optics offer Hi-LumeĀ® multi-coated lenses. The lenses optimize target resolution, contrast, and low-light performance. All hand-fitted internal assemblies are triple spring-tensioned for absolute shockproofing, even under severe recoil. They are vibration resistant, even on extended vehicular patrols.
