The Viridian EON 1x20 Red Dot offers ten settings for its 2MOA dot reticle. When rail space is limited the EON 1x20 Red Dot provides performance in a compact design. Its ergonomic controls allow shooters to make adjustments without taking their eyes from their target. The EON 1x20 Red Dot can be mounted directly to a picatinny rail with the included see-through riser.
