The Trijicon ACOG 3x30 Rifle Scope Chevron 7.62x51 175gr Dual-Illuminated Red Reticle (SKU TA33-C-400379) is a compact fixed 3x ACOG with a 30 mm objective and a red chevron bullet drop compensating reticle cut for 7.62x51 NATO with a 175gr bullet, lit by fibre optics in daylight and a tritium lamp after dark with no battery of any kind.
How It Compares
This is the heaviest calibration in the TA33 range: 7.62x51 with a 175gr match bullet, which is the load most 7.62 semi-automatic marksman rifles are built around. The red crosshair cut for .308 168gr is the other heavy-cartridge TA33 and uses a finer aiming point; the red chevron for .223 62gr is the same pattern on a 5.56 rifle, and the red horseshoe dot for 7.62x39 is the intermediate-cartridge option. Browse all rifle scopes, the Trijicon ACOG rifle scopes range or the full Trijicon optics range.
Ideal For
- 7.62x51 semi-automatic marksman rifles running a 175gr match load

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?
7.62x51 NATO with a 175gr bullet. A 168gr .308 load is close but not identical, and the holds will shift slightly.
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 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.
