Trijicon 4x32 ACOG Rifle Scope Matte 6.8 Red Horseshoe/Dot w/ Picatinny Adapter

The Trijicon 4x32 ACOG rifle scope with red horseshoe/dot reticle is a compact 4-power optic built for shooters who need reliable, fast-target acquisition across variable lighting. Originally designed for the U.S. Marine Corps and special operations, the ACOG has earned its reputation through proven field performance and minimal moving parts—meaning fewer ways for things to fail when it matters. This matte-finish version comes set up for 6.8 SPC rifles with a Picatinny flattop adapter, ready to mount and shoot right out of the box.

The reticle shines via dual illumination: fiber optics gather ambient daylight to keep the red horseshoe/dot visible in bright conditions, while tritium takes over at night without requiring a battery. That "always on, always ready" approach means you're never caught with a dead optic. The scope is nitrogen-purged to stay fog-free in temperature swings, and the fixed-power design keeps the internals simple and rugged. Trijicon specs these to handle recoil across an extreme caliber range and to meet military drop-test standards—it's shock-resistant gear, not range toy.

The Bindon Aiming Concept (BAC) design lets you keep both eyes open while aiming, preserving situational awareness in the field. The red horseshoe/dot reticle doubles as a rangefinder and bullet-drop compensator calibrated for 6.8 SPC out to 800 meters, so you can make holdover calls without guessing. Eye relief sits at 1.5 inches and field of view spans 36.8 feet at 100 yards—enough for hunting and medium-range tactical work where a 4x magnification balances power with light transmission and a wider sight picture.

Specifications

Frequently Asked Questions

Is the Trijicon 4x32 ACOG compatible with my rifle?

This scope includes a Picatinny flattop adapter (TA51) thumbscrew mount, designed for AR-platform and flattop-receiver rifles. The reticle is calibrated specifically for 6.8 SPC cartridges. If your rifle uses a different receiver profile or caliber, you may need a different mount or reticle pattern.

Does the ACOG need a battery?

No. The fiber-optic and tritium illumination system is battery-free and self-adjusting. Fiber optics brighten the reticle in daylight, and tritium takes over in low light automatically. Some other ACOG models offer user-adjustable LED brightness with a single AA battery, but this 4x32 model operates without one.

What comes in the box?

The scope ships with a Picatinny flattop adapter (TA51), a lens cloth (TA64), lens cleaning pen (TA56), lanyard assembly for adjuster caps (TA71E), Trijicon logo sticker, manual, and warranty card.

Can I use this scope for long-range hunting or shooting?

The 4x32 is optimized for medium-distance work. The 4x magnification and 36.8-foot field of view make it quick for closer targets and faster target acquisition, while the red horseshoe/dot reticle provides ranging and holdover marks out to 800 meters on the 6.8 SPC. For distances beyond that or for pure long-range precision, you may prefer a higher-magnification optic.
