I am aware of the laws pertain to CTAR barrel. I am fairly good friends with TV, and have learned alot from him, this is one of the things I have learned. I am still waiting an official response from Jon.
If TV is doing it with no problems, and I am able to leftorize mine with no probs (involves removing and reinstallation of the barrel) than I fail to see why I even need a gun smith let alone Jon. He is quite busy as it is and the wait times already seem to be horrendous.
And if they sell me a barrel, what is stopping me from installing it myself? If they wont ship/sell it uninstalled, what is stopping me from doing what TV does on his own once I receive my newly barreled firearm?
See the problem is people will still do this stuff anyway and there is so many ways to still get around this whole "only NS is capable" rule.
