Trijicon ACOG 3.5x35mm Scope

The Trijicon ACOG 3.5x35mm Scope is a fixed power, compact scope 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. It is available in several different reticle options and reticle colors.

Trijicon ACOG 3.5x35mm Scope Features

Always On, Always Ready

Most ACOG models are battery free, featuring a tritium/fiber optic illuminated reticle that automatically adjusts the brightness based on available light.

Take Control

Several ACOG models are designed with a user adjustable brightness setting powered by a single AA battery. The 3.5×35 LED and 4×32 LED models both offer six adjustable brightness settings.

Rugged, Reliable Housing Design

Fixed power design allows for minimal moving parts to create a nearly indestructible sighting system.

“Both Eyes Open” Design

“Both eyes open” shooting using Trijicon’s Bindon Aiming Concept (BAC) feature allows for improved situational awareness.

Outstanding Clarity

The quality of the glass and multi coated lenses maximize light gathering capabilities and clear field of view with zero distortion.

Exact Target Distances & Holds

Most ACOG models feature a bullet drop compensating and target ranging reticle for decisive aiming.

Combat Proven

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

Shock Resistant

Proven to withstand recoil from a .22LR to a .50BMG and everything in between. Easily passes U.S. Military drop test requirements.

Waterproof

Exceptional waterproof performance that exceeds military standards. Dry nitrogen filled to eliminate fogging. This optic is tested to withstand and perform in extreme cold and heat with dry nitrogen filled housing that mitigates fogging.

Bindon Aiming Concept

Although human vision is based on a binocular or two eyed vision of an image, traditional compact scopes 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 user in quick target acquisition and improved performance.


Utilizing BAC

When tracking a moving target with your shooting eye through a scope, the image appears blurry as the compact scope 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 moving onto the target, you will not notice any magnification, all that will be seen is the illuminated reticle. Once you slow 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:

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

    Shipped fast and excellent pricing. I called before ordering to see how new the optic was to gauge how much life the tritium had left. Customer service was super nice and knowledgeable. I ordered the optic the following day. The eye relief on the 3.5×35 ACOG is much more forgiving than the 4×32 which is nice since I wear glasses and I don’t like getting my lenses scuffed by the aperture. Trade off in eye relief is .5x magnification, field of view, and weight. This optic is noticeably longer and heavier than the 4×32 TA31RCO but that eye relief makes up for it. Clarity is what one comes to expect from Trijicon, impeccable. The purchasing experience from Kenzie’s optics can be described as the same. Quality people, quality optics, and top notch prices. Honestly, don’t waste your time looking elsewhere. Thank you Trijicon for making awesome optics, thank you Kenzie’s Optics for being an awesome business! I’ll be back for sure!
