Trijicon ACOG 3.5x35 Scope, Dual Illuminated Red Crosshair .308 Ballistic Reticle w/TA51 Mount

ACOG 3.5x35 Scope, Dual Illuminated Red Crosshair .308 Ballistic Reticle with TA51 Mount

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:

• Bullet Drop Compensating & Ranging Reticles
• Illuminated Reticle
• Fixed Magnification
• Both Eyes Open Design
• Superior Quality Glass Lenses
• Waterproof to 100 Meters (328 ft.)
• Rugged Aluminum-Alloy Housing
• Combat Proven
• Powered by 1 AA battery
• 6 manually adjustable brightness controls

Bindon Aiming Concept

Human vision is based upon a binocular (two eyes) presentation of visual evidence to the brain. The word binocular literally means using both eyes at the same time. We most often associate this word with binocular instruments such as field glasses or a binocular microscope. These instruments specifically strive to present the object to be viewed the same way to both eyes.

Vision research material was examined for its assistance to understand the optically aided weapon aiming process. Three major types of optical enhancement were compared. There are strong customer preferences in reticle designs, some simple reticles enhance the speed of target acquisition, others allow for greater precision in a given time limit.

The simple substitution of a bright red dot for the usual cross-hairs makes it very easy to keep both eyes open. Just as in the Single point or Armson O.E.G. sighting, the brain merges the two images. During dynamic movement, the scene through the telescope blurs because the image moves more rapidly due to magnification. The one eye sees the bright dot against the blurred target scene, so the brain picks the scene from the unaided eye. The shooter swings the weapon towards the target while perceiving the dot indicating where the weapon is pointed. As soon as the weapon begins to become steady in the target area, the brain switches to the magnified view.

A long search was made to try to combine the speed and non-battery features of the Singlepoint or Armson with the precision of the telescopic system. This discovery was made several years ago. Trijicon has sponsored research in the field of human vision to better understand this generic phenomenon. Although the study concentrated on the Armson O.E.G., some aspects are applicable also to the Bindon Aiming Concept.
