Ok, thanks for the info. So then it is possible for him to fly into town with it and do a PPT at an FFL? I had always figured it needed to be sent to the FFL. If this is the case then it give me options.
I have a BB that I bought, I can probably mail it to him and have him install it. Will I be required to pay tax on the rifle?
Anyone know of an FFL that might do this in the LA area?
