Trijicon ACOG 4x32 Dual Illum Green Chevron M150 TA51 Mount 100229

This is the Army’s "RCO" equivalent, specifically optimized for the M4 Carbine and its 14.5" barrel.

While most ACOGs use red illumination, this specific model features a Green Chevron, which many shooters find easier to pick up against dark backgrounds or in transitional light.

The Army Standard

• M150 Calibration: Unlike the A4 model meant for 20" barrels, this BDC is calibrated for the trajectory of a 62gr 5.56 NATO round fired from a carbine-length barrel.

• Green Dual-Illumination: The fiber optic tube gathers ambient light for a bright daytime reticle, while tritium provides a constant green glow in total darkness.

• The Full Tactical Kit: This model typically ships as a complete "combat-ready" package, including a KillFlash anti-reflection device and flip caps to protect the glass in the field.

• Battle-Tested Eye Relief: Designed for the high-stress environment of a carbine, it maintains the classic 1.5-inch eye relief that allows for the Bindon Aiming Concept (BAC)—shooting with both eyes open for maximum situational awareness.

Key Specifications

Why Choose the M150 over the A4?

If your primary rifle is a 14.5" or 16" AR-15, the M150 is technically the "correct" choice for your ballistics. Plus, if you find that your eyes track green faster than red—a common trait for many shooters—this green chevron is often considered the "secret menu" upgrade of the ACOG world.
