Building on the success of the original SMS the SMSc delivers an updated more durable design crafted from reinforced nylon glass-filled polymer. It offers the choice between a hard-dipped acrylic lens or a crystal-clear glass lens ensuring exceptional clarity and resilience. Specifically designed for EDC and single-stack pistols the SMSc is a compact tough red dot sight built to withstand the daily wear and tear of regular shooting. The SMSc maintains its iconic low-profile design allowing shooters to co-witness with standard iron sights thanks to its unobtrusive frame and rear iron sight notch. Staying true to SHIELDs philosophy weve eliminated unnecessary features offering a clean simple sight with just one point of focus. No oversized housing blocking your view.
