The Trijicon ACOG 6x48 Rifle Scope Horseshoe/Dot .308 Red Reticle (SKU TA648-308H) is the long-range ACOG: fixed 6x magnification, a 48 mm objective and a red horseshoe and dot bullet drop compensating reticle cut for .308 Winchester and 7.62 NATO, lit by fibre optics in daylight and a tritium lamp after dark with no battery of any kind.
How It Compares
The horseshoe is the difference here: where the chevron gives a fine point of aim, the horseshoe is a shape the eye finds faster, which takes some of the sting out of a fixed 6x optic at closer range. The red chevron and the green chevron are the finer-aiming-point versions of the same 6x48, the red chevron with a factory-fitted RMR solves the close-range problem with a separate red dot instead, and the green M240 horseshoe dot is cut for the machine gun.

Ideal For
- .308 and 7.62 NATO rifles that need reach but still see close work
- Shooters who find a horseshoe quicker to pick up than a chevron
- Open country and pale backgrounds where a red lamp reads more clearly than green

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?
.308 Winchester and 7.62 NATO. The stadia below the horseshoe are the drop holds for that cartridge.
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.
Does it come with a mount?
Yes — a TA75 Picatinny rail adapter with Colt-style thumbscrews is included.
Can I shoot with both eyes open?
Yes — the ACOG is designed around the Bindon Aiming Concept for both-eyes-open shooting at speed.
How heavy is it?
36.9 oz (1,046 g). This is the biggest ACOG Trijicon build, and it is a substantial weight on a rifle.
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.
