Not a MB owner, but I do have a particular interest in gun laws in MD, and this post caught my eye:

This member is from MD, and his pic shows that he has:
1) a suppressor, which requires registration with the state, and special permission from your local PD,
2) 2 "assault rifles" (under MD's definitions) which are nearly impossible to get cleared for purchase,
3) several 30rd mags, which are flat-out illegal to purchase in MD,
4) and what appers to be an M203 grenade launcher under one of the ARs, which is flat-out illegal in MD...
I'm assuming that since this guy owns a 2004 E55 AMG (which has an MSRP of $80,000+) he is LOADED, and well-connected, so I suppose that explains why he can own things that 99% of the citizens in Maryland can't even dream of owning. But I find it to be a bit off-putting, and bordering on being a braggart.
Such a display has nothing to do with "2A rights" and everything to do with this member saying "I'm rich and well-connected, and so I get a "pass" on all the cool stuff, while the VAST majority of the law-abiding citizens in this state get routinely hassled for trying to buy a Glock...
I'd bet this member on your MB forum has one of those ultra-rare "Maryland Permit to Carry a Handgun" cards, due to his position of privilege...
Wonder how much money he donates to SAF and MSI?
Just sayin'...
