Shield Sights SMS2 Mini Sight Glass Red Dot

The Shield Sights SMS2 Mini Sight uses a crystal-clear glass lens and a low-profile design for a clear sight picture with compatible mounting setups. Its auto brightness adjustment, SHIELD footprint, and reinforced nylon glass-filled polymer housing make it a practical option for everyday shooting applications.

The sight uses a red LED and is powered by one CR2032 battery installed from underneath. Its patented mechanism supports co-witnessing with standard iron sights, while the unobtrusive housing and rear iron sight notch help preserve a streamlined sight picture.
