-Dont piss off warden. Check, dont want to do that, hence the question, wondering if others have done similar and if its a legit way of operating.

-FAL, so yes can do one round, and simply not take a mag, hadnt even thought of that.

Figured assembly would be follower, spring, block, base plate. No destruction, of any parts.

This is simply a question to stay on the right side of the law. Id rather spend the 30 something on the fuel to get there, the ammo, etc, than on a mag I dont really need. If I really need it, then so be it. Maybe Ill put a call into the DOW, and see what they say. If the reaction/answer is anything but "oh yeah that's fine" then go for the mag.
