Jordan just Plug the gas port inside the barrel it'll make it perfectly legal then, heres a cool way to do it, if you notice on the middle of barrel thier is a gas port, drill the top of barrel rite above the gas port, then put a pin in the little gas hole then resoder and and file smooth, now the barrel is pluged, only way to tell is dropping a cleaning rod down and listen for the pin, but you can't tell from the outside. makes it look good

Cheers BIG MIKE
