Red dot sights, are almost always zero power, or one power. Same thing. This means they do not magnify. A red dot sight is not for precision shooting, but rather very close or very fast shooting. Much of our military uses red dot sights on their small arms because the hit percentage is drastically higher than with iron sights. Competitive speed shooters also use red dots on their handguns for the same reason. The larger the dot, the quicker most people find they can find and shoot their target. Shot gunners are not left out either. A red dot is ideal for hunting turkey or deer, and some people even use red dots for target games like trap, skeet, and sporting clays.
