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. ## Author John B.
