My VFC KAC PDW has 14mm, but had to use a hammer to "slide" it on the rail. The quick release mount is only good for a small rail on a pistol such as my M1911. My rifle fits it extremely tight and I will most likely not be able to ever take it off.
People who are new to lasers:
A laser is a tool to pin-point where a bullet or BB will hit at a set distance. When adjusted, don't expect it to be accurate at "every" distance. Choose the distance you are comfortable with and adjust it accordingly. DO NOT SHINE IN ANY EYE. Some lasers are weak enough not to damage an eye easily, but this laser is extremely powerful and will damage any eye.
