On what mount can you install UTG OP3 Mini Micro? And with which optics can you share the same mount? In this article we look in detail into the UTG OP3 Mini Micro red dot mounting surface.
UTG OP3 Mini Micro uses the same footprint as Shield RMSc standard.
That means that you will be able to use the same red dot mount and red dot plate as Shield RMSc uses.
In other words, any red dot mount or plate made to fit RMSc footprint will also work for your UTG OP3 Mini Micro.
You can see more red dots compatible with Shield RMSc footprint standard in this article.
Shield RMSc footprint consists of four sockets in the corners of the sight and of two screw holes in the rear of the sight.
The front as well as the rear socketes are 17mm / 0.66 inches far from each other. From the rear sockets to the front sockets the distance is 32,8mm / 1.29 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 rear 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.
