Product Info for Trijicon 1.5x16S Compact Dual Illuminated Low Height Q-LOC ACOG Scope

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. The ACOG body is designed to be extremely rugged and reliable. Wrapped in a smaller package, at 5.1 ounces (without mount), this ACOG is perfect for fast-moving tactical teams operating in close quarters or for speed-oriented competition venues. The forged 7075-T6 aircraft-grade aluminum alloy housing provides for a nearly indestructible sighting system. No other magnified optic has been used more in combat than the Trijicon ACOG. 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 1.5x16 models because of the larger field of view (7.4 degrees) and eye-friendly design.image

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.
