From the manufacturer

The Primary Arms MRSC Micro Reflex Sight now comes with AutoLive(R) technology paired with the extremely popular green reticle illumination. The AutoLive feature turns off after sitting still and will automatically turn on at the slightest motion helping to conserve battery life. This Micro Reflex Sight is optimized for compact and micro compact pistols for concealed carry as it features a slightly smaller 21mm lens to keep the profile as slim as possible when mounting on smaller pistols eliminating any overhang on the slide. Even though the lens is smaller than the mini, the square profile offers an unobstructed field of view allowing you to have a clear sight picture every time you present your pistol. It utilizes the RMSc footprint for a wide range of compatibility with milled slides and adapter plates and houses a bottom mounted CR2032 battery offering up to 40k hours of battery life on the medium setting. With 10 total illumination settings, and a daylight bright 3 MOA green dot, this reflex sight is sure to be quick to pick up and easy to use. The lens is fully multicoated for scratch and fog resistance and the 6061 Aluminum housing is extremely durable. If, you are looking for a new red dot for concealed carry you can't go wrong with the Primary Arms MRSC. Precision for any budget. Classic Series(TM) optics and accessories are perfect for the budget-focused marksmen. All Classic Series products come with a lifetime warranty, showing their commitment to guaranteed quality.
