<< What is the point of buying the kit unless you intend to modify the weapon? Even if it is legal to purchase - which, in many states, it is NOT - the intent is to commit an illegal act. >>
This is 100% BS, leave the gunsmithing and advice to those who know.
Anyone who needs info on this feel free to email or PM me, I can point you in the correct, cheap and LEGAL direction.
