So my Saiga as it sits is almost 18.5 inches... I would like to take 4.5 inches off of the barrel and permanently attach a 5 inch monster brake on it.
My question is, in order to do this, for a few moments in its life, the Saiga will have a barrel length under 18 inches...
What do I need to do to be in compliance?
Say the feds raid my house, right as I am making adjustments
In reality, I was wondering if they can retroactively bust you, say "You had to cut the barrel length before you added the brake, so therefore you broke the law."
