In 2009, the U.S. Marine Corps selected the TRIJICON ACOG 3.5x35 Scope, Dual Illuminated Red Horseshoe / Dot M249 Ballistic Reticle, 9.0 MOA RMR Sight and LaRue Tactical Mount (TA11SDO-CP) as its Squad automatic-weapon Day Optic (SDO). The SDO will mount on the M249 light machinegun to assist gunners in target detection, recognition and identification. This model includes the Trijicon RMR, providing the operator with quick target acquisition at close quarter distances or when vehicular mounted.
With its dual-illuminated reticle, the Trijicon ACOG provides shooters with a distinct aiming point in all light conditions - without batteries. Powered by a tritium-phosphor lamp, the gunsight's reticle glows in low-light conditions, while advanced fiber optics automatically adjust the brightness level and contrast of the reticle in brighter light conditions.
The Trijicon ACOG Scope incorporates the innovative Bindon Aiming Concept (BAC). This revolutionary, both-eyes-open aiming method provides you with "instinctive" target acquisition and increased hit potential. And, the scope's ranging is built into many of its reticles, so you only need to set zero once for a multitude of ranging distances.
Broad-band, anti-reflective coated lenses provide superior clarity and light gathering capabilities with zero distortion. The ACOG also offers a Large Eye Volume, which allows you to quickly acquire targets, even if you're not positioned perfectly behind the scope. Of course, once the target is acquired, you can then take time to position your eye and compose your shot.
The ACOG is crafted with a tough, military-grade, aluminum-alloy housing and is waterproof to depths of 500 feet / 150 meters - making it nearly indestructible. Only the prism housing moves, so it's much more rugged than conventional designs. And the ACOG does not require failure-prone batteries - so you can rely on it to perform in practically every situation.
