Overview

The TA02-C-100833 puts Trijicon's new red MRAD chevron tree reticle in the LED version of the 4x32 ACOG. The optics and footprint match the dual-illuminated TA31 MRAD, but illumination comes from an LED powered by a single AA battery with six user-selected brightness settings instead of fiber optics and tritium.

The MRAD reticle is the reason to pick this over the familiar 5.56 BDC models. Consistent mil subtensions let you record holds for your own rifle and ammunition, which suits suppressed builds, 300 Blackout running supersonic and subsonic loads, and any carbine whose trajectory does not match a stock BDC.

Trijicon rates battery life at over 12,000 hours on setting 4 with the supplied alkaline battery at 70 degrees F. Other listed specs: 1.5 inches of eye relief, a 7 degree field of view (36.8 feet at 100 yards), 17.5 ounces, forged aluminum housing, submersion to 66 feet, and the TA51 flattop thumbscrew mount.
