ss, there's no eye relief issues with a red dot, like on magnified optics. In fact, the further forward you place it, the faster it is to acquire the dot/target. No kidding. No alignment issues, once zero'd. You don't have to have the dot right in the center of the viewing field - it can be off to the side, low, at the top, whatever. When you align dot/target, no matter where the dot is inside that field of view - the rifle is pointed directly at what the dot is on. That's where speed comes in.
