This is a premium design, front facing mount only, styled with cool textures to suit the HDR50 airsoft revolver.
It also includes a couple of plugs the can be pushed into the holes as a cover. A tiny center hole is built in for easy removal of the covers.
The HDR 50 fits perfectly in the custom designed mount. Best secured with two screws 4-5mm diameter and 40-45mm length.
