The Sightmark Element 1x30 Red Dot Sight is a 2 MOA red dot sight, that gives you the ability to keep both eyes open. The Element features a practical clamp mount, reducing bulk and creating a sleek, streamlined design. The Element is designed to protect the newest feature of adjustment caps with raised edges. A rugged and compact aluminum alloy housing keeps the Element 1 inch shorter than the competition and provides increased durability in the field. This versatile red dot is night vision compatible and works in conjunction with magnifiers to help with further distances. Waterproof up to 3 ft. and shockproof up to 3 ft. on concrete, the Element provides anywhere from 100-15,000 hours of battery life from one CR2032 depending on which brightness setting is being used. The Element 1x30 Red Dot includes flip-up lens covers, a CR2032 battery and user manual.
