The ACOGs are internally-adjustable, compact telescopic sights with tritium illuminated reticle patterns for use in low light or at night. Bindon Aiming Concept (BAC)* models feature bright daytime reticles using fiber optics which collect ambient light.

The ACOGs combine traditional, precise distance marksmanship with close-in aiming speed. Although the ACOGs have many features which are very advantageous for military use, they were developed by Trijicon without government funding.
Designed for use with the M16 family, every feature of its mechanical and optical design was chosen for a single purpose: to provide increased hit potential in all lighting conditions -- without failure-prone batteries.

Trijicon is proud to offer the new Trijicon ACOG® TA33. This new 3x30mm model is designed for law enforcement and military applications — where the combination of ample magnification, low light capability and long eye relief make the TA33 the Trijicon ACOG of choice. This rugged, dependable aiming system is available with Bullet Drop Compensated (BDC) reticles calibrated to the trajectory of the .223 and .308 cartridges and provides precision aiming for targets out to 600 meters. The extended eye relief allows the TA33 to be mounted on larger caliber.

The Trijicon ACOG TA33 is totally battery-free, featuring a red or amber chevron aiming point. The TA33 takes advantage of the innovative Bindon Aiming Concept™ (BAC). In tandem with scope magnification, this revolutionary both-eyes-open aiming method provides the shooter with “instinctive” target acquisition and increased hit potential.

Weighing in at less than seven ounces, which includes the mount, the Trijicon ACOG TA33 is perfect for the latest patrol rifle or carbine. A forged, 7075-T6 aluminum alloy housing gives it durability beyond the call of duty.
