Fenix ALG-18 rail mount for flashlight on weapon or railing

I bought it to mount it on a jointed arm that should support cameras or photo accessories. I use it to orient the light of a Fenix ​​TK20R torch in a precise point, so I can see the detail of the well-lit area, to paint or assemble the pieces of scale model cars. The only flaw is that the tires come off from the smaller clamp socket. I've already glued them 2 times. For the rest it's fine, it doesn't have to do anything great....
