The Trijicon 3.5x35 ACOG rifle scope is a combat-proven dual-optic system built for shooters who need both rapid close-range target acquisition and precision at distance. This 3.5x magnification scope pairs the legendary ACOG design with an integrated 3.25 MOA Trijicon RMR Type 2 red dot, giving you the flexibility to engage threats from across a room or out to 1000 meters. The reticle is factory calibrated for .223 / 5.56 NATO on flat-top rifle rails, making setup straightforward for AR platforms and other modern carbines.
Illumination comes from a dual system: fiber optics gather ambient light during the day to keep the red crosshair bright without batteries, while tritium takes over at night for reliable glow in total darkness. The Bindon Aiming Concept design lets you shoot with both eyes open, increasing situational awareness when it matters most. At just 14 ounces (without the RMR or mount), the ACOG stays lightweight enough for extended shooting sessions, and the forged aluminum housing is built to handle hard use in the field or at the range.
Included in the package are the RMR Type 2 pre-mounted on the ACOG, a TA51 flat-top adapter, LENSPEN lens cleaner, lanyard assembly for adjuster caps, and a manual to get you up to speed. The 2.4-inch eye relief and 10mm exit pupil deliver a comfortable sight picture, while 3 clicks per inch at 100 yards give you precise bullet-drop corrections out to distance.

The Trijicon 3.5x35 ACOG is designed for flat-top AR-platform rifles and any firearm with Picatinny rails that accept the TA51 mount. The scope comes with the TA51 adapter included, so it's ready to mount on most modern rifle platforms once you attach it to your rail.
Yes. The integrated Trijicon RMR Type 2 red dot gives you fast target acquisition at close range, while the 3.5x ACOG reticle is calibrated for precision shooting out to 1000 meters. You can use whichever aiming system best suits your range, making this a true do-it-all optic for tactical, hunting, or general rifle applications.
During daylight, fiber optics collect and channel ambient light to illuminate the red crosshair. At night or in low light, tritium gas vials glow continuously to provide a visible red reticle. This means the scope stays functional in any lighting condition without relying on batteries.
The package includes the 3.5x35 ACOG scope with the RMR Type 2 already mounted, the TA51 flat-top adapter for your rifle rail, a LENSPEN lens cleaner, a lanyard assembly for the adjuster caps, and the ACOG user manual.
