Trijicon ACOG 4×32 ECOS Tritium Scope / 3.25 MOA RMR Type 2 Combo

The Trijicon ACOG 4×32 ECOS Tritium Scope w/ 3.25 MOA RMR Type 2 Combo was designed for both Close Quarter Battle and long distance use. The dual sighting system gives the user a distinct tactical advantage with the option of either the ACOG or the RMR Type 2 sight. With the quick target acquisition of the RMR Sight or the precise aiming capabilities provided by the magnified 4 power ACOG, the user has the ability to select the proper aiming solution for the situation at hand. No tools are needed for windage and elevation adjustments because the ECOS also features external windage and elevation adjusters, making it waterproof up to 11m without caps.

Trijicon ACOG 4×32 ECOS Tritium Scope / 3.25 MOA RMR Type 2 Combo Features

Always On, Always Ready

Most ACOG models are battery free, featuring a tritium/fiber optic illuminated reticle that automatically adjusts the brightness based on available light.

Take Control

Several ACOG models are designed with a user adjustable brightness setting powered by a single AA battery. The 3.5×35 LED and 4×32 LED models both offer six adjustable brightness settings.

Rugged, Reliable Housing Design

Fixed power design allows for minimal moving parts to create a nearly indestructible sighting system.

“Both Eyes Open” Design

“Both eyes open” shooting using Trijicon’s Bindon Aiming Concept (BAC) feature allows for improved situational awareness.

Outstanding Clarity

The quality of the glass and multi coated lenses maximize light gathering capabilities and clear field of view with zero distortion.

Exact Target Distances & Holds

Most ACOG models feature a bullet drop compensating and target ranging reticle for decisive aiming.

Combat Proven

No other magnified optic has been used more in combat than the ACOG.

Shock Resistant

Proven to withstand recoil from a .22LR to a .50BMG and everything in between. Easily passes U.S. Military drop test requirements.


Exceptional waterproof performance that exceeds military standards. Dry nitrogen filled to eliminate fogging. This optic is tested to withstand and perform in extreme cold and heat with dry nitrogen filled housing that mitigates fogging.
