I’m active duty military and I’m moving from Washington state to Maryland very soon. I have acquired numerous firearms while in Washington and I’m trying to rap my head around all the BS laws. First off, most of my firearms I have built myself, to include: AR-15 pistol (5.56) 10.5in barrel, AR-15 (5.56) 16in barrel, AR-10 (.308) 16in barrel, AK-47 (not built), and recently acquired a dedicated 9mm stripped lower (glock) that I plan on building into a pistol with brace. All other firearms are either legal or need to be registered once I establish residency. My question is about my black scary guns which have been built after 2014. I have read where active military may be exempt from certain actions but can’t find it in black and white. I’m looking into buying HBARs for my AR-15s and outfitting them prior to entry. Is my AR-10 legal as is? Please provide links if possible. Thanks in advance. Also I hope to meet some like minded people once I get there so anything about memberships, meetings, etc would be greatly appreciated.
