The SMSc is a compact version of the successful SMS line of reflex sights designed specifically for use on smaller single-stack, personal defense pistols. The optic sports an updated design with improved durability and reduced profile and is offered in both the classic hard-dipped acrylic or glass lens configurations each sporting a clear, non-tinted coating allowing for a crystal clear sight picture. The SMSc is also fully backwards compatible with SHIELD Sights universal RMS/SMS mounting footprint while retaining an IP67 waterproof rating, auto-brightness function and a 20,000-hour single-battery life of all previous SMS models. This model comes in an acrylic lens configuration and features an all-black finish and a 4 MOA dot. One CR2032 battery is included along with a mounting kit consisting of two sets of two screws (2-M4x8mm; 2-M4x10mm), two hex wrench tools, four nylon washers, and one Reece's Law battery cover. An optic cover is also included for storage and transportation use.
