ACO Sight Review: Aimpoint Carbine Optic

A simple, durable, and affordable sight for carbines / Photo by Rab Cummings

The Aimpoint Carbine Optic is a basic red-dot system that comes ready to mount on any rifle with a Picatinny-style rail. The height of the mounting bracket works in conjunction with the stock geometry of standard AR- or AK-type rifles to give the shooter a proper cheek weld. The sight has an ergonomic on/off knob with 10 settings: the off position, and nine levels of brightness, ranging from a dim dot for low light to ultra bright for sunny conditions.

Tough bugger
I have been using and abusing my ACO for several months, running it on different rifles, and it has taken all the punishment in stride. Battery life is laughably long: A single 3V lithium battery provides more than a full year of continuous use. The price is right too: At $393, it's a good value.

Notable Features
—The ACO is built on an aluminum housing and coated with non-reflective anodizing.
—The sealed windage and elevation knobs move the point of impact ½ inch per click at 100 yards.
