This started when someone commented that you can buy an upper without going through an FFL.
Say you have a Maryland legal HBAR AR. Can you legally swap out an upper with a NON-HBAR upper?
For example - Can you legally put a Colt 6920 upper with the M4 Barrel with Grenade Launcher cutout on a Colt 6721 lower?
Common sense tells me no but I know common sense and MD gun laws don't always align. This is an academic debate - my guns are all legal and I have zero desire to change uppers on them.
