Welcome to CGN.
I am very interested in the possibility of getting a custom stock, or several, made if they are not prohibitively expensive. Specifically I'm wondering about the possibility of buttstock storage of magazines.
I have also been interested in the idea of a sort of tool box that transforms into a little reloading bench, for reloading on the go. Something that you could use some c-clamps to attach to a tailgate or tabletop, then pack up without fuss or leaving holes.
I guess it all depends on if you have minimum order requirements, I know how quickly the costs of doing one-off custom orders can become prohibitive.
