If it was home-made after 1968, you may no longer possess it in the state of Maryland as of Oct 1, 2019. Period.
If they decide to go California-style with this, Maryland would need to create a whole system around applying for, recording of, granting to, and securing serial numbers for home-made firearms. It would make those who never hear about this into criminals and those who do not want to serialize w/state have to relocate or destroy their handiwork.
Tyranny in either case.
Absolutely correct.
Scenario 1 (passes as written): ALL home built firearms as of Oct 1, 2019. Are banned for possession. So move them out or destroy.
Scenario 2: Registration scheme. Apply to MSP for a serial number (they might allow a custom one), pay a fee (who knows how much), will likely be on a 77R (I think they have no other scheme). They do their checks, give you a number. That number is engraved on the receiver, firearm, etc. This would likely apply to all home builds in possession.
Problems with the above: Scenario 1 is on it's face unconstitutional (and I'm not talking tyranny, etc). You cannot order a destruction of a legally possessed firearm in the state. Be it a home built HBAR, preban AR, Colt, Glock, Ruger 10/22, and fill in any other platform you wish.
Problem with Scenario 2 is the Fiscal Note. This thing will be EXPENSIVE. LGQL business is already pegged at 3.4 million. This thing is who knows but at least as much if not much higher. There are tons of 80's in this State. Any they know it's not enforceable. Door to door is in violation of the 4th (illegal search and seizure). Crazies could care less about 3 years on top of murder. Heck they anticipate to be dead any way. The other issue is date of manufacture. All of the 80's made in this State were pre-ban (prove otherwise). How will they handle that? This thing is a nightmare.
Remember this whole thing was sparked by Del Dumas with regards to the Glock 19 by an 18 year old. This is an intelligent kid (AP classes) but with some mental issues.
