The Trijicon ACOG 2x20 Rifle Scope Crosshair Dual-Illuminated Green Reticle (SKU TA47-C-400341) is the compact ACOG: fixed 2x magnification, a 20 mm objective and a plain green crosshair etched into the prism, lit by fibre optics in daylight and tritium after dark with no battery of any kind.
How It Compares
This is the green-lamp version of the plain-crosshair 2x20. Green tends to be the easier lamp to pick out against woodland and foliage, red the easier against snow and pale ground; the red crosshair is otherwise the identical optic. The reticle carries no bullet drop compensation, so it is not tied to a cartridge — for holds cut to a pistol-calibre carbine see the ACOG 2x20 RTR 9mm PCC, and for a triangle aiming point instead of a crosshair the red 9.2 MOA triangle.

Ideal For
- Close-quarters carbine work where 2x is enough magnification and speed matters more
- Woodland and foliage backgrounds where a green lamp stands out better than red
- Builds that need the optic off and back on again without losing zero, using the Q-LOC mount

Frequently Asked Questions
Does it need batteries?
No — the reticle is lit by fibre optics in daylight and tritium in the dark. There is nothing to switch on and nothing to run flat.
What calibre is the reticle calibrated for?
None — it is a plain crosshair with no bullet drop compensation, so it is not tied to a cartridge.
Why choose green over red?
Green tends to stand out better against woodland and foliage, red against snow and pale ground. The two optics are otherwise identical.
Does it come with a mount?
Yes — a Trijicon Q-LOC Technology quick-release Picatinny mount, which is removable rather than integrated.
Can I shoot with both eyes open?
Yes — the ACOG is designed around the Bindon Aiming Concept for both-eyes-open shooting at speed.
What warranty does it carry?
Trijicon's Limited Lifetime Warranty. The tritium lamp carries its own multi-year term from date of manufacture.
Is this a genuine Trijicon product?
Yes — factory-new, genuine Trijicon, covered by Trijicon's Limited Lifetime Warranty.
