The Fastfire4 is the multi-reticle red dot in the Burris Fastfire family. It is feather light at under 2oz with a doctor/vortex footprint. It has a unique set of features designed for 3-gun, action shooting, and mounting on shotguns for bird and clays.
The Fastfire4 has an oversized objective window allowing for a more forgiving field of view for action shooters in unusual shooting positions. While small and light, Burris managed to fit in ambient light sensor. When placed in auto-brightness mode, the Fastfire4 will automatically dim and brighten to compensate for lighting conditions. The Fastfire4 offers 4 different reticle options which can be cycled by pressing the button on the right side of the optic: A 3MOA precision dot, an 11MOA dot, and two 50MOA circle dots, one with a horizon line, which Burris calls a wing-dot reticle. I think the latter reticle looks more like a Pokeball. The horizontal line is presumably for shotgun users, who might use it as a guide for their shot spread.
I prefer multi-reticle red dots in Falling Plates matches. I like to switch between a precision dot and a circle dot reticle at different target distances or stages. Large circle reticles allow me to bracket my steel targets for faster follow up shots.
Burris also included a plastic hood which can be fitted to the rear of the reflex sight, converting it into a closed emitter red dot. This allows the red dot to be resistant to rain and dirt that can plague reflex sights. Anybody who’s struggled to wipe off the wet inside of a reflex sight, will know how useless they can become in the rain. This hood can be especially useful when mounting this sight on a shotgun.
The Fastfire4 is not perfect. While it has a rated 26,000 runtime on a CR1632 battery, and an auto shut-off after 8-hours, it lacks motion-activation. The unit has to be manually activated before use, precluding my consideration for its use for Home Defense firearms or Concealed Carry. As a minor peeve, the front lens bulges past the frame and I often found my palm print on the lens after racking my pistol slide. This could have easily been fixed by extending the lip of the lens frame a few millimeters. And finally, the Fastfire4 isn’t cheap with a street price around $360 which makes it one of the more expensive MRDs on the market.
Despite these drawbacks, the pluses definitely outweigh the minuses for this optic, especially for action shooters. The Fastfire4’s reticle options are ideally suited for the falling plates and bullseye matches I compete in. I just wish it were cheaper and offered in RMR or MOS cut for my other pistols and mounts.
