Burris FastFire III Red Dot Reflex Sight 3 MOA Features:

The Burris FastFire III is a light and tough reflex red dot sight that gives the user an unmistakable advantage with superior speed and accuracy compared to iron sights, no matter the ambient light. This compact red dot features an automatic brightness sensor that matches the dot to the conditions, preventing bloom or washout, backed up by 3 manual brightness settings. The convenient battery compartment can be accessed through the top of the optic and doesn't require the optic to be removed to change the battery, preventing the need to rezero. To improve battery life the sight includes an automatic time-out feature after 8 hours, that extends life up to 5 years. This 3 MOA dot is ideal for use on long guns, or for shooters who prefer less of the target to be obscured by the dot when mounted on a handgun.
