Okay tmiles, now I see.  First you said ‘using a Utah permit’ but now you mention ‘temporary residency’ which makes more sense, but like you, I would never do it.  I could go to another state and buy a non-HBAR AR15, but that would be breaking Maryland law, so I would never do that.

Michael Hoffman, people moving to Maryland with an non-HBAR A15 must have purchased it prior to 10/1/2013 or it illegal to bring in and they must register all hanguns within 90 days of residency. Handguns sold in Maryland cannot have magazine with over 10 rounds.  The Free State indeed.  [V]
