Dealers deal with this kind of transaction, all the time. You will know how receptive yours is when you go in and ask him for a copy of his FFL, that should be signed and dated. Now, whomever you buy your gun from, you wil pay them, provide the FFL copy and they will ship to your dealer. Just make sure you have them clearly put you name on the shipping for your dealer clearly sees who it's for. This is the typical transaction say for purchases through GunBroker. ...
The above will vary depending on what state, you live in. ...
Good luck and;
Be Safe !!!
