Bottom Line

This sight is built to handle the tough stuff, for a price.

If you’re someone who likes their optics to scream “durability” and “reliability,” you’re definitely in the right place! Grab a cup of joe and sit back, because we’re about to dive deep into the high-definition world of Trijicon’s ACOG riflescope

  • Battery-free illumination
  • Always illuminated reticle
  • Built like a tank

What Customers Say​

Easy to mount. Easy to sight in. Easy to shoot. Tough as nails.

I bought this scope a few years ago. Still mounted to my rifle, the glass is still really clear it holds up really well to the saltwater environment and harsh winter in my home town. Holds zero dropped it a few times oops but never questioned it. Well worth it.



Now, let’s not jump the gun here. The Trijicon ACOG is a fine choice, but there’s a big wide world of optics out there.

What Customers Say

Absolutely love this thing! Mounted on my Marlin 1895gs chambered in 45-70 govt with an American Defense T1 quick-release mount. Holds up to the recoil and honestly, I couldn’t have picked a better optic and mount. The setup was zeroed in 4 rounds and after that, I felt like I couldn’t miss! I keyholed rounds between 50 and 100 yards all day. This sight didn’t miss a beat and I will be buying more. I love Sig optics and they have yet to let me down and this one is worth every penny!

What Customers Say

One of the best red dots on the market for this price. The mount is high quality, and was able to co-witness on my Vltor CASV handguard (the one that dog legs onto the upper receiver), by removing the spacer. The lowest settings can really be fine tuned for use with NV, and the 4 upper setting should get you through most lighting situations. It’s an awesome value.

Chad J. Sullivan

This sight is awesome I had it installed in 10 minutes. Took it to the range sighted it in at 25 then made small adjustment at 50 yards. Afterwards I set my steel silhouette up at 200 yards had no problem hitting it consistently with 55 grain fmj. Would recommend to anyone.

First Impression: Trijicon ACOG Red Dot

When we first got our hands on the Trijicon ACOG Red Dot, we were all “oohs” and “ahhs”. It’s like the off-road vehicle of red dot sights – rugged, steadfast, and ready for whatever Mother Nature throws at it.

The field of view seems huge when you look through it, and even though it isn’t a true 1x, it’s still pretty quick for target acquisition.

Trijicon ACOG Red Dot Features

Battery-Free Operation

No batteries? No problem! With Trijicon’s clever use of fiber optics and tritium, your sight will be always-on, no matter what. It’s like magic, but it’s not – it’s just darn smart engineering.

Its battery-free operation is also one of the ACOG’s advantages against a red dot sight. Discover which is really better between these two optics in our ACOG vs Red Dot comparison.

Believe it or not, your only complaint may be that this illumination system is too bright! Many people cover part of the fiber optic tube with electrical tape to tone down the brightness.

Dual-Illuminated Reticle

Looking through Trijicon ACOG Red Dot

Day or night, rain or shine, your target is always in sight with the dual-illuminated reticle. It’s like having night vision, only without those funky goggles.

Rugged Construction

This sight is built to handle the tough stuff. Whether you’re caught in a downpour or dropping it onto a rock (though we really don’t recommend it), the ACOG can take a lickin’ and keep on tickin’.

With a fixed zoom, there are no adjustment mechanisms to break, and as a result, the ACOG has legendary for its durability.

Lifetime Warranty

Trijicon’s got you covered with their lifetime warranty. They’re basically saying, “We trust our product that much.” And if that doesn’t make you feel all warm and fuzzy, we don’t know what will.
