The Trijicon ACOG 1.5x16S Rifle Scope RTR .223 55gr Dual-Illuminated Red Reticle (SKU TA44-C-400390) is the smallest ACOG Trijicon build: 1.5x magnification, a 16 mm objective and a red Rapid Target Reticle with .223/55gr bullet drop marks, lit by fibre optics in daylight and a tritium lamp after dark with no battery of any kind.
How It Compares
At 1.5x this is a close-quarters optic first and a magnified sight second, which is why the RTR reticle is built around a large ring for speed rather than a fine crosshair. The same body with a reticle cut for a 9mm carbine is the ACOG 1.5x16S RTR 9mm PCC, while the red ring with 2 MOA centre dot and the green ring with 2 MOA centre dot drop the bullet drop marks for a plain ring and dot.

Ideal For
- Close-quarters carbine work where speed matters more than magnification
- Shooters who want battery-free reliability with nothing to switch on
- Builds that need the optic off and back on again without losing zero, using the Q-LOC mount
