You do know that most if not all guns can be modified , you can either buy the parts ,just by browsing the firearm supported forums or fan forums and you can see what others have done , =even this forum offers tons of valuable experience , When I bought a Kel-tec sub 2000 .40sw , I had know idea the kinds of mods that could be done , if your interested look of fan sites for particular guns , you'll see some pretty wild configuration of modern guns, I modified my AK with parts from a shotgun and it looks awesome , plus I recently painted my Sub 2000 and AK in camoflage patterns and they look sweet!
Its endless what you can do , dont be afraid , try it
! If your a machinist , the doors wide open!!
