Designed for today's slimmest carry guns, the SHIELD SIGHTS SMSc Mini Compact Red Dot Sight with Glass Lens features a more streamlined and more durable design. Ideal for EDC and single-stack pistols, the SMSc (Shield Mini Sight Compact) is crafted from reinforced nylon glass-filled polymer so it's more than tough enough to withstand daily wear and regular shooting. The SMSc maintains the original SMS's low-profile design that allows shooters to co-witness with standard iron sights. SHIELD's minimalist design philosophy keeps your target area clear of obstructions, and the crystal-clear glass lens provides the highest level of clarity. Up to 20,000 hours of battery life on one CR2032 battery. 100% waterproof to IP67 standards.
