Holosun continues to break the mold and buck the traditional trends with its creativity and innovation. The 403GL is a small compact red dot sight with side battery housing and H/L adjusting turret options. Utilizing eye safe, low drainage LED technology, the lifetime for one CR2032 battery can be up to 5 years.
