ACOG (Advanced Combat Optical Gunsights) - 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. 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.

Standard Features:

- Eye-friendly advantage. Conventional riflescopes offer only a tiny exit pupil, requiring careful eye positioning directly behind the eyepiece. ACOG provides maximum eye latitude behind the scope, for easier target acquisition. This greater aiming freedom is especially important in stressful field situations requiring quick aiming.

- Multi-coated lenses provide maximum optical performance

- 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.
