Trijicon 4x32 ACOG Rifle Scope, .223 Amber Crosshair, 3.25 MOA Red Dot RMR - Black

The Trijicon 4x32 ACOG rifle scope with integral 3.25 MOA RMR red dot is a proven dual-optic system built for shooters who need both close-quarters speed and extended-range precision. This .223-calibrated combo pairs the legendary ACOG's battle-tested reliability with a co-mounted RMR for fast target acquisition—a no-compromise setup favored by serious marksmen and tactical shooters. Whether you're training at the range, hunting across varied terrain, or running dynamic scenarios, this scope adapts to your distance and situation without the fumble of mounting or zeroing separate optics.

The ACOG's 4x magnification and 32mm objective deliver a clean, bright sight picture with a 7-degree field of view and 36.8 feet at 100 yards. The ranging reticle—an amber-glowing crosshair fueled by Trijicon's battle-proven tritium illumination—appears sharp black in daylight and glows amber when light fades, with no batteries or adjustments needed. Bullet drop compensation is built into the reticle out to 600 meters, so you can hold center and let the optic geometry do the work. The RMR's compact 3.25 MOA dot pairs seamlessly with the ACOG for targets that need a faster sight picture than magnified reticle work allows.

Build quality reflects Trijicon's no-nonsense heritage: forged aluminum housing, solid 1.5 inches of eye relief, and a rock-solid TA51 thumbscrew flattop mount included. The scope weighs 14.96 ounces without the RMR and measures 5.8 inches end to end. Everything you need ships in the box—scope caps, the TA51 mount, a lens pen, a lanyard assembly for the adjuster caps, and the full manual.
