You can do whatever you want as long as you don't take photos and spray them all over the internet.
Also, "constructive intent" isn't what most people think.
Example: a prosecutor wants to hit you with NFA charges for having an unregistered SBR;
Scenario 1: you own 1 AR-15 with a short barrel and no other firearms. You have a stock but it's not on the rifle.
Scenario 2: you own 2 AR-15s, one has a short barrel and the other a long barrel. Short barrel doesn't have a stock on it but long barrel does.
Scenario 3: you own 1 AR-15 with a short barrel, no stock on it. You own a stock and a brace.
Scenario 1 you *can* get popped for constructive intent and an NFA because you have no non-violative configuration for your rifle and are readily able to convert it into a non-compliant state.
Scenarios 2 and 3 don't have this problem because you have configurations readily available to you that are compliant to the NFA.
Of course this is just mental masturbation because this would never happen but it's important to know the minutiae of the law. The State will wield it and fuck you with it, best to know what you can do back.
