My God man, do you know what a STRAW MAN PURCHASE IS? It is a serious federal (and sometimes state) firearms crime!
It is where you purchase a firearm for someone else. You have just admitted you intend to make a straw man purchase and documented it on Free Republic. I wouldn’t be so sure that big brother isn’t watching.
My advice to you is to now document that you are really going to buy it for yourself. And may after you have used it a while you will tire of it and give it to your son, and have an FFL do the transfer and indicate to the FFL that you no longer like it, so you have an independent witness.
Ignorance of the law is not an excuse.
It is completely legal to purchase a firearm and to gift it to someone else. Even Sarah Brady bought a hunting rifle and gave it to her son.
Lighten up and do some reading. It is not against federal law to gift your kid a gun, unless he is a prohibited person.
