I'm sure some of us, especially myself, engage in some form of universal background checking when we sell guns either on a forum site, or through other internet sites. In its most simplistic form, and one that I can see posing no threat to our 2A rights is what I do when I sell a handgun to another in another state. I use an FFL to effect the transfer through another FFL in the buyer's state. Here, I leave a legal paper trail from my end, which leads to a paper trail at the other end. The buyer will have to go through his own background check in order for his FFL to release the gun to him. If the buyer fails the check, his FFL is obligated to return the handgun to my FFL, who again, will require that I get another background check to release the handgun to me. In the rare event such as this, the seller has the option of deducting all the costs so far incurred in this failed transaction, and returning the remaining funds to the buyer, who may very well be in jail or has fled the jurisdiction. To me, this is an acceptable form of universal checks, Now, where I draw the line is having to go through all that crappola if I want to sell or give a brother, a daughter, a nephew, a childhood friend a gun; that is exactly what the anti's want, to make it a total nightmare, and a costly one at that, to transfer gun ownership between two legal and law abiding citizens.
