Form 1 ?

[737Driver]

Going to sbr my gsg-5P. On the form 1 it asks for overall length under the firearm description. Since I will not be purchasing a stock for it until I get the tax stamp, and haven't decided on a fixed or collapsible model. Do I put the current overall length down and then amend the overall length later, or do I need to figure out what the length will be with a stock and put that down?
Thanks!

Fixed or collapsible does not matter. ATF has said that firearms with collapsible stocks are to be measured with the stock fully extended.

Most collapsibles end up at about the same length as a fixed full size stock when all the way out so.....

ok, I will figure out the overall length with a stock.
