Trijicon ACOG TA11 3.5x35mm
The Trijicon ACOG TA11(Advanced Combat Optical Gunsight) TA11 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.
Trijicon ACOG TA11 3.5×35 scope with Red Chevron BAC Reticle- The ranging reticle is calibrated for 5.56 (.223 cal) flat-top rifles to 800 meters. The chevron reticle is designed to be zeroed using the tip at 100 meters. The width of the chevron at the base is 5.53 MOA which is at 19” at 300 meters. This allows range estimation for silhouette targets.
Trijicon ACOG TA11 Features
Battery Free Illumination
Features a tritium/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 a nearly indestructible sighting system.
“Both Eyes Open” Design
The Trijicon ACOG TA11 can be used as a CQB sight when shooting “both eyes open,” utilizing the Bindon Aiming Concept (see below).
Superior Quality Glass Lenses
Multi-coated lenses provide superior clarity and light-gathering capabilities with zero distortion.
Fewer moving parts than a variable optic equals more durability.
No other magnified optic has been used more in combat than the ACOG.
Proven to withstand recoil from a .22LR to a .50BMG and everything in between. Easily passes U.S. Military drop test requirements.
Dry-nitrogen-filled to eliminate fogging. Five times more waterproof than military standard requirements.
Limited Lifetime Warranty
Tritium lamp is warranted to illuminate for 15 years on fiber optic scopes and 10 years on non-fiber optic scopes.
Bindon Aiming Concept
Although human vision is based on a binocular or two-eyed vision of an image, traditional compact riflescopes present a monocular view of the target. This monocular view significantly 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 use 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: better situational awareness, a far superior 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.
When tracking a moving target with your shooting eye through a riflescope, the image appears blurry as the compact 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 if necessary. 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:
- First, OPEN BOTH EYES, and hold you index finger out in front of you line of sight on a fixed object.
- Next, CLOSE your non-shooting eye and note the position of finger on target.
- Then OPEN BOTH eyes, keeping finger on target.
- Finally, CLOSE opposite eye and note position of finger on target.
If your finger/aiming point does NOT move, that is your dominant eye. If your finger/aiming point moves off target at a great distance, your OTHER eye is dominant.
