The FastFire 3 is a miniature reflex sight designed for mounting to pistol slides, rifle handguards, shotgun receivers, and other platforms with a compatible mounting footprint. As a reflex sight, it uses a partially reflective lens to project the illuminated dot onto the glass without the enclosed tube design of traditional rifle scopes or larger red dot optics. The open window design gives the shooter a wide, unobstructed field of view for fast target acquisition at close range without restricting peripheral vision. Multiple brightness settings adapt the dot intensity to ambient lighting conditions, and an automatic brightness mode uses a built-in light sensor to adjust the setting in real time. The 3 MOA dot size appears precise at moderate distances while remaining fast to find in close-quarters situations. The FastFire 3 is compatible with a wide range of pistol slide mounting plates and dovetail adapters, making it one of the more versatile miniature reflex sights in terms of platform compatibility. For shooters who want a compact, lightweight reflex sight for a handgun, defensive carbine, or shotgun, the Burris FastFire 3 is a well-regarded miniature optic with a proven track record across carry, competition, and duty firearm applications.

Frequently Asked Questions
What does 3 MOA mean for a reflex sight dot?
3 MOA refers to the apparent diameter of the illuminated dot at 100 yards — approximately 3 inches. A 3 MOA dot is smaller and more precise than a larger 8 MOA dot, making it better suited for moderate-distance shots where precision matters.
What firearms is the FastFire 3 compatible with?
The Burris FastFire 3 is designed for mounting to pistol slides (using a compatible adapter plate), rifle handguards, shotgun receivers, and any firearm with a compatible mounting footprint or accessory rail.
Does the FastFire 3 have automatic brightness adjustment?
Yes. The FastFire 3 includes an automatic brightness setting that uses a light sensor to adjust dot intensity based on ambient lighting, in addition to manual brightness settings for shooter-controlled intensity.
