HS512C’s best features the multi-reticle system, which allows me to swap between a 2-MOA dot, a 65-MOA circle and a combination of dot and circle. It also has aggressive shake-awake technology, which will auto shutoff the optic if it lacks movement. Pair that with the solar backup panels and you get an optic that lasts 5 years on a single CR2032 battery. This red dot is Brand New. Never mounted to rifle.
