The Trijicon ACOG 2x20 Rifle Scope RTR .223 Dual-Illuminated Red Reticle (SKU TA47-C-400388) is the compact ACOG with a red Rapid Target Reticle cut for .223, lit by fibre optics in daylight and a tritium lamp after dark with no battery of any kind. Fixed 2x magnification, a 20 mm objective and a Q-LOC quick-release mount in the box.
How It Compares
At 2x this is a close-quarters optic first, so the RTR is built around a large ring for speed with bullet drop marks beneath it for the reach a plain dot cannot give you. The same body with holds cut to a pistol-calibre carbine is the ACOG 2x20 RTR 9mm PCC. If you do not want a cartridge-specific reticle at all, the red 9.2 MOA triangle, the red crosshair and the green crosshair carry no bullet drop compensation. Browse all rifle scopes, the Trijicon ACOG rifle scopes range or the full Trijicon optics range.
Ideal For
- Close-quarters .223 and 5.56 carbines 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
