Convert a registered full auto to semi?
Slap your self in the face. Do it now.
No. As far as the ATF sees it. "Once a machinegun, always a machinegun." The only way to make a F/A into a S/A is by torch cutting the receiver into three pieces and using the rest of the parts to build a new (semi auto only) gun on a new receiver.
There are some folks that are in the buisnes of taking post-sample F/A MP5s and cutting them up and building S/A MP5 short barreled rifles.
Stopping power: The power some guns have to make you stop what you are doing and get your wallet out.
