FINALLLY got my clearance on an AR - been waiting since 10 January. My FFL told me that the MSP waited so long that my clearance is only good for a couple of days before it expires.
Problem with getting our money back (in my case anyway) is, there's a 15% charge. It'll cost me $82-92 to get out but it may come to that.
My 30 days are up next week. I'm going back to The Gun Shop and see how much of my deposit (on a gun they didn't have) I'm able to get back. We'll end up in North Carolina in a couple years anyway so I'm really losing interest in jumping through Maryland's hoops.
Shouldn't take more than 7 days. Ask your FFLs before you buy. By law there is no point in waiting more than that.
I checked again this morning, The Gun Shop in Essex is where I purchased. They had some paperwork come back from 1/10.
No FFL is going to release a regulated gun without the paperwork coming back. If it comes back disapproved, it's the FFL's ass on the line.
