The Viridian RFX42 Enclosed Green Dot Reflex Sight (Viridian part no. 981-0176) is a compact enclosed-emitter sight for concealed carry and defensive pistols. The enclosed design protects the emitter from dust, moisture and debris, which maintains a clear, uninterrupted sight picture in all conditions. A crisp 3.5 MOA green dot gives fast target acquisition, and Instant-On activation powers it up the moment you draw. It mounts directly to pistols cut for the Shield RMSc footprint.
