You won't have to pay an FFL to do a transfer for you (on a C&R). That should pay for the license itself the first time you use it from the sound of what the fees are getting to be.
It gets shipped right to your 'licensed premises'.
As pointed out,,keep the book work up to date,,not really hard to do.,,and don't start 'dealing' w/a C&R. BATF really frowns on that.
You are open to 'compliance checks' of your records and actually your inventory on your license.
C&R's have the check made on an appointment basis as they do not have business hours listed on their license (you are not a business).
You also have the option then to have the compliance check of your records done at the BATF's field office rather than your licensed premises.
It's infrequent that they check on C&R's, but they do on occassion. Especially when they have suspicions of dealing going on.
You will run up against 01FFL's(dealer) that won't take your 03FFL(C&R) for a purchase. They just feel it's in some way taking business away from them, though I never figured out how,,you still pay me the price I want for anything I have.
The fact that they can't check the C&R FFL# on the BATF EZ-Chek website really bothers many, so they don't accept them.
Some places allow discounts, some don't.
Many Military Surplus type firearms dealers allow C&R FFL holders the same prices as 01Dealer FFL's. Sometimes they might not get the same shipping prices,,especially true with handgun sales.
I don't really see a downside to them if this is your hobby. That's what the license is for. Makes it easier to acquire and also sell & ship the firearms when you do dispose of one.
As stated,,many firearms other than the 50+ y/o rule are C&R.
Some are individual guns that collectors have requested the status,,some others are a specific mfg'r & model w/o regard to the age or year of manufacture. The Colt SAA Revolver falls into that catagory.
