Steiner MPSc Reflex Red Dot Sight 1x21-19mm 2MOA Reticle Black. Its ultra-compact enclosed design is purpose-built for modern compact and slimline pistols delivering a durable low-profile optic that carries comfortably and disappears under concealment. Built on the proven MPS platform the MPS-C features a crisp fast-acquiring red dot housed in a fully sealed optical system that resists sweat dust moisture and daily wear. The low deck height and clean sight picture support intuitive both-eyes-open shooting - ideal for rapid threat identification and consistent shot placement in defensive scenarios. Weighing just 32 g and up to 40percent lighter than comparable enclosed red dots the MPS-C minimizes slide mass and preserves the natural balance of your carry pistol. The result is faster follow-up shots improved control and a red dot that feels purpose-built for concealed carry-not adapted from competition use.
