Trijicon TA31F ACOG 4x32 Scope, Illuminated Red Chevron .223 BDC, Flattop Mount – 100215Description
The Trijicon TA31F ACOG is a fixed-power 4x32 riflescope featuring an illuminated red chevron reticle with integrated bullet-drop compensation for .223 applications. Designed around the proven ACOG optical system, the TA31F combines fixed 4x magnification, a wide field of view, rugged forged-aluminum construction, and a reticle that provides both a precise aiming reference and predetermined hold points for longer-range shooting.
The dual-illuminated reticle uses fiber optics to automatically adjust illumination intensity according to available ambient light, while tritium provides illumination in low-light and nighttime conditions. This battery-free illumination system keeps the reticle available without electronic controls or replaceable batteries. The TA31F also supports Trijicon\'s Bindon Aiming Concept for both-eyes-open shooting and includes a TA51 flattop thumbscrew mount for installation on compatible rail-equipped Trijicon TA31F ACOG

Red Chevron .223 BDC Reticle
The TA31F uses Trijicon\'s illuminated red chevron reticle with integrated bullet-drop compensation designed for .223 applications. The chevron provides a highly visible aiming reference while allowing the tip of the chevron to serve as a more precise aiming point.
Integrated BDC references provide predetermined hold points for engaging targets at extended distances without requiring the elevation adjustment to be manually dialed for each range.
Battery-Free Dual Illumination
The TA31F does not require batteries to illuminate its reticle. Fiber optics collect available ambient light during daytime conditions and automatically regulate reticle brightness according to the surrounding environment.
In low-light and nighttime conditions, tritium provides illumination without requiring switches, electronics, or an external power source.
Optical System
The fixed 4x32 optical system combines 4x magnification with a wide 7-degree field of view, providing approximately 36.8 feet of viewing area at 100 yards. Multi-coated lenses are designed to maximize light transmission while providing a clear, high-contrast sight picture.
Bindon Aiming Concept
The TA31F supports Trijicon\'s Bindon Aiming Concept, allowing the optic to be used with both eyes open. This design helps maintain a broader view of the surrounding area while retaining immediate access to the magnified sight picture.
Rugged Construction
The ACOG uses a forged aluminum housing and a fixed-power optical design with minimal moving components. Its rugged construction is engineered to withstand recoil, impact, vibration, and demanding field conditions.
The housing is dry nitrogen filled to help prevent internal fogging and sealed for waterproof performance.
Mounting
The TA31F includes the Trijicon TA51 flattop thumbscrew mount for installation on compatible rail-equipped platforms. The thumbscrew design provides a secure mounting interface while allowing the optic to be removed when necessary.
What\'s Included
Buyer Value
The Trijicon TA31F combines a fixed 4x32 optical system with a red chevron .223 BDC reticle, battery-free fiber-optic and tritium illumination, and rugged forged-aluminum construction. Its wide field of view, Bindon Aiming Concept capability, integrated ranging references, and included TA51 flattop mount make it a durable and versatile magnified optic for compatible .223 platforms.
