The Trijicon ACOG 1.5x16S Scope is a fixed magnification riflescope with an illuminated reticle pattern for use in any lighting conditions. Dual illumination provides two sources of battery-free illumination fiber optics and tritium. The fiber optics use ambient light to automatically adjust the brightness level and contrast of the reticle to available light conditions. The tritium-phosphor lamp glows in low-light conditions. No tools are needed for windage and elevation adjustments because the ACOG features external adjusters. All adjuster caps are provided with a lanyard assembly to minimize the loss of caps. This model provides weapons like the M16/M4 with excellent fire control capability. Targets are easier and quicker to acquire through the 1.5×16 models because of the larger field of view and eye-friendly design. The Trijicon Compact ACOG Mount w/ Q-LOC Technology features a Mil-Spec drop test rated 6061-T6 aluminum design, with an easy to use one handed tool less mounting system. The spring-loaded design allows for constant retention and maintaining of zero even if the knobs are not tightened. The mount boasts a low weight and low profile design with superior return to zero performance and is compatible with any Mil-Spec or NATO Picatinny rail.
