Trijicon ACOG RCO 4x32mm Green Chevron Reticle – TA31RCO-M150CPG

$1,319.48

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.

Trijicon ACOG RCO 4x32mm

The Trijicon ACOG RCO 4x32mm with a green chevron reticle is made 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 m utilizing the Bullet Drop Compensator.

No tools are needed for windage and elevation adjustments because the Trijicon ACOG RCO 4x32mm features external adjusters, making it waterproof up to 11 m without the caps. Mounting bosses are integrated into the housing by the eyepiece to allow the easy addition of a Trijicon RMR (not included).

ACOG RCO 4x32mm Features

Battery Free Illumination

Features a tritium and fiber optic illuminated reticle that automatically adjusts the brightness based on available light.

Rugged Aluminum Alloy Housing

Forged 7075-T6 aircraft aluminum alloy housing provides for an indestructible sighting system.

“Both Eyes Open” Design

The Trijicon ACOG TA31 can be used as a CQB sight when shooting “both eyes open,” utilizing the Bindon Aiming Concept (see below).

Great Quality Glass Lenses

It is multi coated lenses provide great clarity and light gathering capabilities with zero distortion.

Fixed Magnification

Fewer moving parts than a variable optic equals more durability.

Combat Proven

No other magnified optic has been used more in combat than the ACOG.

Shock Resistant

It is proven to withstand recoil from a .22 LR to a .50 BMG. It easily passes U.S. Military drop test requirements.

Waterproof

Dry nitrogen filled to eliminate fogging, and is five times more waterproof than military standard requirements.

Limited Lifetime Warranty

The tritium lamp is warranted to illuminate for 15 years on fiber optic scopes and 10 years on non fiber optic scopes.


Bindon Aiming Concept

Human vision is based on a binocular or two eyed vision of an image, while traditional riflescopes present a monocular view of the target. This monocular view decreases vision capabilities and makes it difficult to acquire and track targets.

Traditionally, “both eyes open” aiming has been widely used with iron sights or reflex style sights, but used with a magnified scope was often deemed implausible. The Bindon Aiming Concept (BAC) is a method of combining “both eyes open” aiming while using a magnified scope.

Shooting with “both eyes open” offers several advantages to the user such as, better situational awareness, a far greater sense of balance, a wider field of view, and far less eye strain. These advantages aid the shooter in quick target acquisition and improved shooting performance.


Utilizing BAC

When tracking a moving target with your shooting eye through the Trijicon scope, the image appears blurry as the riflescope moves due to the magnification. This blurriness forces the brain to automatically switch eye focus and take in target data from the non shooting eye (non magnified). Due to the use of a highly illuminated aiming point in most Trijicon optics, the reticle remains visible in the shooting eye and your brain will superimpose the aiming point onto the non magnified target.

When the weapon is moving onto the target, you will not notice any magnification, all that will be seen is the illuminated reticle. Once you slow the weapon onto the target, the target will “zoom” in, allowing you to identify and engage more accurately. This aiming concept happens naturally, without conscious thought, for those with equal or close to equal vision in both eyes.


Finding Your Dominant Eye

In order to maximize the potential of “both eyes open” aiming, you must know which eye is dominant. To determine this, conduct the following test:

  1. First, OPEN BOTH EYES, and hold you index finger out in front of your line of sight on a fixed object.
  2. Next, CLOSE your non shooting eye and note the position of the finger on target.
  3. Then OPEN BOTH eyes, keeping the finger on target.
  4. Finally, CLOSE the opposite eye and note position of finger on target.

If your finger or aiming point does NOT move, that is your dominant eye. If your finger or aiming point moves off target at a great distance, your OTHER eye is dominant.
