The ACOG or ‘Advanced Combat Optical Gunsight’ is widely known as being used on military rifles around the world, including here in Australia. The biggest feature of the ACOG that stands out, is the illuminated reticle that is solar powered. The scope absorbs light and uses that energy to charge it.
Quick Take
The Trijicon ACOG 3.5×35 is best judged by how it fits the rifle, not just by the spec sheet. Glass quality, reticle design, controls, mounting height and real-world use matter more than chasing one big headline number.
- Best use case: match the optic to the rifle?s actual job before worrying about brand hype.
- Check before buying: reticle style, eye relief, turret feel, weight and mounting requirements.
- Do not forget the mount: good rings and correct height are part of the optic system.
The scope can be fired with both eyes open, in what is called the ‘Bindon Aiming Concept’. Another great feature of the ACOG is that it is completely waterproof.The military has a history of selecting optics that are solid and reliable such as the Nightforce NX8.
The Trijicon ACOG is no different, being extremely well made and able to take a beating. The optics service around the world is a testament to its durability. The glass in the ACOG is incredibly clear. As expected with a high-end optic, the glass quality does not disappoint and is very crisp. The red dot reticle proved to be a great match for the .223 WFA1-L rifle being used with it.
The reticle is etched into the glass which boosts its clarity.For the military the ACOG is used when clearing rooms all the way out to engaging targets at 500 meters. From a hunting perspective, the ability to use the optic for engaging game at close ranges as well as at extended ranges is a massive plus.
The scope has a battle proven track record coupled with excellent ability to accompany almost any short to medium range firearm. Is the optic recommended for a precision rifle? No. But it is an extremely capable optic for most firearms.
