For these reasons, the advent of red dot and holographic optics has been revolutionary. You can take that further and include pointing devices such as lasers and night vision optics. With combat taking place at almost any time, any place, and with the advent of covert, search-and-destroy type ops, you can see how being functional at night is crucial. But as a recreational or competitive shooter, red dot optics offer a clear advantage for a different reason. First, let's take a look at the similarities and differences between red dot/reflex sights and holographic sights.

Currently, you can find reflex red dot optics in two configurations. The "tube-style" red dots typically sit in a mount raised above the bore of the rifle, and have a battery source on the top or to the side of the reticle tube. Aimpoint, Vortex, Bushnell, Trijicon, Leupold, and others feature optics with this configuration. A second type is the so-called "Heads-up" or single-lens reflex sight. These very small sights usually attach directly to a rail and are popular positioned on top of ACOG's, variable power scopes, or on offset rails such as the 45 degree rails you see on 3-Gun setups. Trijicon, C-More, and Docter are some of the more well-known manufacturers of heads-up style reflex sights.

The big advantage of using red dot or holographic sights on AR style rifles involves the ability to shoot better in low light conditions and also to focus on the target instead of the reticle. The most proper way of utilizing rapid acquisition sights is to shoot with both eyes open, focusing on the target, and allowing the dot to sit over your target. In fact, if you focus your eyes on the dot itself, often times it will appear blurry. Proper aiming allows quicker acquisition of the target and allows you to keep your eyes downrange. Even though the technology inside each type of optic is different, their description of use and functionality are essentially the same. Personal preference comes into play quite a bit here, and trying out both types is highly recommended before tossing down the cash to get one. You can expect to spend anywhere from $200-600 for top-quality tube style and holographic sights, and close to $1000 for ACOG style optics. Needless to say, it pays to do your homework when selecting an optic. Hopefully, this clears up some of the confusion on the differences between reflex and holographic sights and allows you to make a more informed decision for your needs.
Be safe and see you next time.
