You do not have to be a licensed dealer to buy a firearm. If you are not a licensed firearm dealer (also called an FFL Holder), you must make arrangements with an FFL Holder in your state to receive the item and transfer it to you. Virtually anyone who is involved in the sale or distribution of firearms is an FFL Holder, including gun shops. You must make arrangements with your FFL Holder before placing a bid on an item. By contacting the FFL Holder before bidding, the buyer can verify that all state and federal laws will be observed. For most firearms, the buyer must be able to pass a background check.
So technically you can buy it, but an FFL is still involved, so the checks and balances are there.
I stand corrected. Thanks fellas.
