as I understand it . . . you can't take it out of state, etc.
Not exactly correct. You do have to provide notice. However, if you have some place you go regularly, say you go shoot at your farm one state over, you can in essence give notice once and get approval for the rest of the year.
as I understand it, there are legal consequences if you don't update your address promptly,
The same is true for my driver's license, but that's not going to keep me from having one.
WOW, you shaved 4 inches off your plinker shotgun.
I would tend to agree that if you were cutting a shotgun from 18 to 14 it might not be worth it
to me. Cutting something down to 6-10" is a fairly dramatic difference though, and if it adds to the fun factor then why not?
What do you GAIN from it... ? Zero.
Personal enjoyment doesn't count? If we are talking about a single shot shotgun it is mostly going to be for the gee wiz factor. I would not tell anyone that is an unacceptable reason to own a gun though. I do think SBRs and SBS really can offer a dramatic difference in weight and handling and still be very usable, often more so.
I get someone might have personal things that factor in, such as moving every 3 years as part of the military, but it makes little sense to project those factors on everyone or to make a statement that it is per se a PITA. Working in a law office I would really question whether it is too hard for a lawyer to write a letter once every 3 years when he moves.
I think one of the reasons people tend to get more NFA items once they have gotten one is that they realize it really isn't a PIA.
I totally get that some may not want to delve into NFA items. I'd take issue with someone who has never done so characterizing it as a PITA and discouraging others from doing so for that reason.
I look at all of this from a Cost/Benefit perspective. There's little/no upside and a lot of downside, including stiff legal penalties and throwing away probably 3 times the value of the gun on the paperwork and effort. Not for me, thanks. If it's for you, have fun.
I think that those statements would be better if you strategically added the phrase "to me." For example, there is little/no upside to me.
Also, why bother coming to the NFA forum? Or are you talking about this project specifically?
