The Trijicon ACOG 3x24 Rifle Scope Horseshoe/Dot .223 55gr Dual-Illuminated Red Reticle Low Height (SKU TA50-C-400354) is a compact fixed 3x ACOG with a 24 mm objective and a red horseshoe and dot reticle 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
Two builds of this optic exist and the only difference is how high it sits: this is the Low Height Q-LOC, which puts the ACOG close down over the receiver and suits an absolute or lower-third co-witness with iron sights. The same optic on the standard-height Q-LOC is the taller option. With a green lamp instead, the green horseshoe dot on the Low Height mount is the direct equivalent, and if you want a finer aiming point the red crosshair replaces the horseshoe. Browse all rifle scopes, the Trijicon ACOG rifle scopes range or the full Trijicon optics range.
Ideal For
- .223 and 5.56 carbines running a 55gr load
- Builds that co-witness with iron sights and want the optic sitting low

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 horseshoe are the drop holds for that load.
What does the Low Height mount change?
It sits the ACOG lower over the receiver than the standard-height Q-LOC, which suits an absolute or lower-third co-witness with iron sights and puts the eye closer to the bore.
Where do I aim with a horseshoe and dot?
The dot in the middle of the horseshoe is the aiming point. The horseshoe itself is there to catch the eye quickly at close range.
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.
Can I shoot with both eyes open?
Yes — the ACOG is designed around the Bindon Aiming Concept for both-eyes-open shooting at speed.
Is this a genuine Trijicon product?
Yes — factory-new, genuine Trijicon.
