Trijicon ACOG 4×32 BAC Riflescope with RMR, Green Chevron Reticle

Description

Trijicon ACOG RMR Features and Performance

The Trijicon ACOG RMR combo is built for shooters who want a proven fixed-power combat optic paired with a miniature red dot for close-range speed. This TA31-D-100548 configuration combines a 4×32 ACOG with a green chevron .223/5.56 BDC reticle and a piggybacked 3.25 MOA RMR Type 2 red dot, making it a strong fit for defensive rifles, training carbines, and general-purpose 5.56 setups.

The main optic uses fixed 4x magnification and Trijicon’s Bindon Aiming Concept to support fast target acquisition while still giving the shooter magnified capability at distance. Its green chevron reticle is calibrated for .223/5.56 and uses fiber optic and tritium illumination, so the ACOG portion does not rely on batteries for normal use. The included RMR Type 2 adds a fast close-range aiming option with an LED-powered 3.25 MOA dot.

Built from forged aluminum and designed for hard use, this optic package is made to handle demanding field conditions without adding unnecessary complexity. The 4×32 ACOG body stays compact for its capability, while the included Colt knob thumbscrew mount keeps the setup ready for compatible rifle platforms. Shooters who want one optic package that covers close work and longer shots often gravitate toward this style of ACOG and RMR combination.

With 1.5 inches of eye relief, a 36.8-foot field of view at 100 yards, and a .223/5.56 BDC reticle, this setup remains a strong option for shooters who want battery-free magnified reticle illumination with a secondary red dot on top. The Trijicon ACOG RMR is a strong option for users who want magnified precision and fast close-range capability in one field-ready package.
