The Trijicon ACOG 6x48 Rifle Scope Chevron .308 Green Reticle (SKU TA648-308G) is the long-range ACOG: fixed 6x magnification, a 48 mm objective and a green chevron 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
This is the 6x48 with a green lamp, which is the colour that reads best against woodland and foliage where red can wash out. The same reticle with a red lamp is the ACOG 6x48 Chevron .308 Red, the red horseshoe dot swaps the chevron for a horseshoe that is quicker to find at close range, and the red chevron with a factory-fitted RMR adds a red dot on top. There is also the green M240 horseshoe dot cut for the machine gun. Browse all rifle scopes, the Trijicon ACOG rifle scopes range or the full Trijicon optics range.
Ideal For
- .308 and 7.62 NATO rifles that need reach rather than close-range speed
- Woodland and foliage backgrounds where a green lamp stands out better than red
- Shooters who want a fine aiming point without a battery anywhere in the system

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 marks below the chevron are the drop holds for that 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.
Where exactly do I aim with a chevron?
The tip of the chevron is the aiming point. The wide base below it draws the eye in 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.
Is this a genuine Trijicon product?
Yes — factory-new, genuine Trijicon.
