The 4x32 ACOG Riflescope from Trijicon is a battle-tested optic that combines battery-free reticle illumination and weather-sealed construction with Trijicon’s unique Bindon Aiming Concept. This sighting technique allows a shooter to operate with both eyes open, simultaneously targeting through their magnified optic and maintaining situational awareness—a crucial advantage during close-quarter combat and engagements with targets at varying distances. Iron sights atop the ACOG housing provide a secondary aiming option for close-range targets.
This 4x32 configuration of the Advanced Combat Optical Gunsight (ACOG) features an amber-illuminated bullet drop compensating reticle that has a fine crosshair and holdovers calibrated specifically for .308 caliber ballistics. A tritium phosphor lamp provides battery-free reticle illumination by automatically glowing as light diminishes. The reticle’s aiming point can be adjusted in 1/2 MOA increments, and an internal adjustment mechanism allows the ACOG to reliably hold zero. Additionally, this ACOG is outfitted with a TA51 flattop rifle mount that has two thumbscrews for clamp-on attachment to a Colt-style rail.
A folded light path and broadband multicoated optics allow the ACOG to transmit a bright and wide field of view using a relatively compact form factor. Complementing the ACOG's optical system and caliber-specific ballistic reticle is a nitrogen-filled anodized aluminum housing that provides the durability needed for reliable performance in a wide range of shooting conditions.
