The Trijicon ACOG (Advanced Combat Optical Gunsight) is a fixed power, compact
riflescope with an illuminated reticle pattern for use in bright to low/no light. The ACOG is
designed to be extremely durable and reliable. Combining traditional, precise distance
marksmanship with CQB speed, many variants include a bullet drop compensated (BDC)
reticle. Every feature of its design was chosen for a single purpose: to provide increased
hit potential in all lighting conditions.
FEATURES
The TA31RCO is an Advanced Combat Optical Gunsight (ACOG) designed for the US Army's M4 weapon system (14.5" barrel). It incorporates dual illumination technology using a combination of fiber optics and self-luminous tritium. This allows the aiming point to always be illuminated without the use of batteries. The tritium illuminates the aiming point in total darkness, and the fiber optic self-adjusts reticle brightness during daylight according to ambient light conditions. This allows the operator to keep both eyes open while engaging targets and maintaining maximum situational awareness.
Designed to the exact specifications of the United States Marine Corps, the unique reticle pattern provides quick target acquisition at close combat ranges while providing enhanced target identification and hit probability out to 800 meters utilizing the Bullet Drop Compensator.
No tools are needed for windage and elevation adjustments because the TA31RCO features external adjusters, making it waterproof up to 11m without the caps. Mounting bosses are integrated into the housing by the eyepiece to allow the easy addition of a Trijicon RMR® (not included).
The TA31RCO-M150CP also includes:
- 1 Thumbscrew Flattop Adapter for Picatinny Rail (TA51)
- 1 killFLASH® Anti-Reflection Device (TA91)
- 1 Objective & Eyepiece Flip Cap Set
- 1 LENSPEN® (TA56)
- 1 Lanyard Assembly for Adjuster Caps (TA71E)
- 1 Trijicon Logo Sticker (PR15)
- 1 RCO Manual
- 1 Warranty Card
