It's only a sketch, but comments, advices and critics are welcome
I'm not going to manufacture these now, but if I find someone with proper milling machine somewhere around, maybe I will.
Sorry guys, I lost my job and had to sell most of my paintball gear to fill money gap and move to another projects. I'm back on horse now and finnishing 3d model, it should be ready next weekend.
I'm looking for someone in U.S. who is interested in manufacturing these.
