This is how I usually go about it..
1. First, make sure the dealer doens't have the item already in stock. If so, look at the AIM price, add about $45.00- $50.00 to the price and make that offer. ($25.00 for dealer, 20 for shipping). If he won't take that, there is a 90 percent chance he won't order it for you either, so find another dealer.
2. If you can't find one offhand, try this link from gunbroker
http://gunbroker.com/User/DealerNetwork.asp. From there you should be able to locate a dealer. Ask the dealer if he has a FFL on file with AIM. More than likely he will have. If not, he will have to send a signed ink copy of his FFL before you can order your rifle.
3. Negotiate a fee with the dealer for the transaction. I won't do it if it's over $25.00. There are dealers out there who will work with you on the price.
4. Either send your money order for the item, plus shipping in the envelope with the dealers FFL or wait until they get your dealers FFL. In most instances you can use your CC to order. This FFL also covers any future purchases you might want to use the dealer for. I prefer to use my CC just in case they are out of stock when your dealers FFL reaches them.
5. Patiently wait and try to not make the dealer go nuts with phonecalls!
When he calls you, you fill out the normal paperwork as a standard gun transaction, to include the background check. This is when you pay the dealer his fee and whatever he charges for the bg check.
6. Take rifle home and immediately burn through several magazines of ammo!! But then you might not get to do just that immediately if you have wacky gun laws in Illinios. Here in Fl you leave with your rifle the same day.
Good Shooting
