A note of caution (I guess I am the only one who does this).
Check local laws before buying with a C&R license, especially handguns. In Maryland and some other states, only a dealer with a STATE license can legally receive regulated firearms (handguns and "assault" rifles) from another state. State licenses are issued only to dealers, not collectors.
The shippers look at the C&R license and will ship, but the recipient is in violation of the law. (And, yes, "VE HAF VAYS OF FINDINK OUDT".)
Don't flame me on this and don't bother us with blather about rights. I didn't write the laws and am only trying to keep naive people out of trouble. And no, an FFL DOES NOT give anyone the right to violate state or local law.
