The Trijicon ACOG 3x24 Rifle Scope Crosshair .223 55gr Dual-Illuminated Green Reticle (SKU TA50-C-400353) is a compact fixed 3x ACOG with a 24 mm objective and a green crosshair carrying .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
The 3x24 is one of the shortest ACOGs at 4.9 in, and it pays for that with the shortest eye relief in the range — 1.4 in, so it wants mounting well forward of a service stock. This is the green-lamp crosshair on a Low Height Q-LOC mount. The same optic with a red lamp is the ACOG 3x24 Crosshair .223 Red; for a different cartridge the ACOG 3x24 Crosshair 7.62x39 Green is cut for 123gr, and the green horseshoe dot replaces the crosshair with a horseshoe for faster close work.

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?
.223 Remington with a 55gr bullet. The stadia below the crosshair are the drop holds for that load.
How much eye relief does it have?
1.4 in (36 mm). That is very short — the shortest of the compact ACOGs — so it wants mounting well forward of a service stock.
Does it come with a mount?
Yes — a Low Height Trijicon Q-LOC quick-release Picatinny mount, which sits the optic low over the receiver.
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.
