On what mount can you install Burris Fastfire 3? And with which optics can you share the same mount? In this article we look in detail into the Burris Fastfire 3 red dot mounting surface.
Compatible footprint
Burris Fastfire 3 red dot uses the same footprint as Vortex Venom standard (also often reffered to as Docter or Noblex footprint).
That means that you will be able to use the same red dot mount and red dot plate as Vortex Venom or Docter / Noblex uses.
In other words, any red dot mount or plate made to fit Vortex Venom or Docter / Noblex footprint will also work for your Burris Fastfire 3 red dot.

Burris Fastfire 3 pattern
The Vortex Venom footprint consists of four sockets in the corners of the sight and of two screw holes in the central part of the sight.
The front as well as the rear socketes are 20mm / 0.79 inches far from each other. From the rear sockets to the front sockets the distance is 39mm / 1.54 inches. Position of these four sockets corresponds to position of pins that are on a mounting surface of any mount for this standard.
The screw holes are positioned in the central part of the optic device. These function for fixation of the sight to the mounts. These two screw holes are 14mm / 0.55 inches far from each other.
The screws that are to be used for these screw holes are always included in the package with the sight.
