No problem of mine. I suppose you're free to ruin your gun barrels if you want, sort of the same way that I'm free to buy Picassos and use them to start the fires in my fireplace during the winter.

Thanks! Its good to know I'm free to do ANYTHING these days.
I'm also sure that fire would be MUCH more detrimental to your paintings than a plastic tube (with a wire inside it) would be to my Glock barrel.
