A micro red dot (MRD) is a compact, lightweight red dot sight designed for use on firearms. MRDs are typically mounted on the top of the firearm’s receiver or slide and provide the shooter with a precise aiming point. Unlike traditional iron sights, which require the shooter to align the front and rear sights, MRDs project a red dot directly onto the target, making target acquisition much faster and easier.
MRDs offer a number of advantages over traditional iron sights. They are much faster to use, especially in close-quarters combat situations. They are also more accurate, as the shooter does not have to worry about aligning the front and rear sights. MRDs are also less fatiguing to use, as the shooter does not have to focus on two different points of aim.
