Hit fast in any light
The ACOGs are internally-adjustable, compact telescopic sights with tritium illuminated reticle patterns for use in low light or at night. Many models feature bright daytime reticles using fiber optics which collect ambient light.

Features and Benefits:
Models with cross-hair reticles are luminous in the dark, but show black in daylight, for ideal aiming in any light.
BAC models feature reticles illuminated both day and night. A fiber optic collects ambient light during the day, and a tritium lamp lights the pattern at night. The Tritium lamp lasts 20 years. Amber color is used in compact ACOG models because its brighter.
Forged 7075-T6 aircraft aluminum alloy housing, precision machined to exacting tolerances, and hard-anodized to match the upper and lower receiver of the M16 rifle.
Internally adjustable. Because only the prism housing moves, the ACOG is much more rugged than conventional designs.
Aerospace seals make the ACOG waterproof to Navy Seal depths.
