The TRIJICON ACOG 4x32 Scope, Dual Illum. Red Crosshair .223 Ballistic Reticle, 3.25 MOA RMR Sight, A.R.M.S. Mount, Dark Earth Brown (TA31-ECOS) is the ultimate sight for both Close Quarter Battle (CQB) situations and longer distance shooting where accuracy and pinpoint bullet placement are required. Trijicon is the first to market with its unique dark earth brown color, a definite factor to concealment - directly contributing to the safety of the operator, who is often in harm's way.
This dual-sighting system gives the shooter a distinct tactical advantage with the option of either the Trijicon ACOG or RMR sight. With the quick target acquisition of the RMR Sight or the precise aiming capabilities provided by the magnified 4 power Trijicon ACOG - the shooter has the ability to select the proper aiming solution for the situation at hand - truly the best of both worlds.
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 4x32 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 large Eye Volume, giving you greater leeway - fore and aft, and from side to side - with which to see through the lens. Of course, once the target is acquired, the ACOG is a trusted ally to help you zero in on a perfect shot.
No tools are needed for windage and elevation adjustments because the ECOS also features external windage and elevation adjusters, making it waterproof up to 11m without caps.
The ACOG is crafted with a tough, military-grade, aluminum-alloy housing and is waterproof to depths of 100 feet - 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.
