Trijicon ACOG 4x32 BAC Riflescope - Red .223/5.56 Chevron (TA31F)
The Trijicon ACOG 4x32 BAC is the optic that made the ACOG a legend: a battery-free, dual-illuminated 4x combat riflescope with a red .223/5.56 bullet-drop chevron reticle. Fiber optics and tritium keep the reticle lit in any light with no batteries, the Bindon Aiming Concept lets you shoot with both eyes open, and a forged aircraft-grade housing shrugs off punishment. It ships with the TA51 flattop mount, ready for your AR.
Key Features
- Battery-free dual illumination: Fiber optics power the reticle in daylight and a tritium lamp takes over in low light, so the aiming point is always lit without a single battery.
- .223/5.56 BDC chevron reticle: The red chevron zeroes at the tip at 100 meters and its ranging stadia are calibrated for 5.56/.223 flattop rifles out to 800 meters.
- Both-eyes-open speed: The Bindon Aiming Concept keeps the bright reticle in your dominant eye while both eyes stay open for fast target acquisition and situational awareness.
- The combat standard: At 4x32, this is the ACOG that set the standard as the most combat-proven magnified optic in the world.
- Combat-proven forged housing: Forged 7075-T6 aircraft-grade aluminum makes for a nearly indestructible sighting system.
- TA51 flattop mount included: Ships with the TA51 thumbscrew flattop adapter to mount on any picatinny flat-top.
- Made in the USA: Built in Wixom, Michigan and backed by Trijicon's limited lifetime warranty.

Forged, Combat-Proven Housing
A forged 7075-T6 aircraft-grade aluminum housing makes the ACOG nearly indestructible. No magnified optic has been used more in combat.
Outstanding Optical Clarity
Precision-ground, multi-coated glass delivers a bright, sharp 4x sight picture edge to edge.
Tool-Free External Adjusters
External windage and elevation adjusters dial corrections in the field, with capped, lanyard-secured turrets and no tools required.
Description
No magnified optic has been used more in combat than the Trijicon ACOG, and the 4x32 TA31F is the model that earned that reputation. Its battery-free dual-illumination system uses fiber optics to gather ambient light for the reticle in daylight and a tritium lamp to keep it glowing in the dark, so the red chevron is always ready without ever touching a battery.
The chevron reticle zeroes at the tip at 100 meters, with a base width of 5.53 MOA for range estimation and a ranging ladder calibrated for 5.56/.223 flattop rifles out to 800 meters. The Bindon Aiming Concept keeps the bright reticle in your aiming eye while both eyes stay open for speed and awareness. Forged from 7075-T6 aluminum and made in the USA, it comes with the TA51 flattop mount and Trijicon's limited lifetime warranty.
Tested to Survive
Every Trijicon optic earns its reputation the hard way, through a battery of punishing tests inspired by real-world use from Alaska to Africa.
