The FastFire III offers upgraded features such as windage and elevation adjustments that don’t require a special tool; a convenient power button with three levels of brightness and an automatic brightness setting and battery access on the top of the sight making it easier to change batteries. We’ve also added a low battery warning indicator and see through protective cap.
