I believe in Arizona it is perfectly legal to purchase a gun and give it as a gift. If the third party gave him the money for the gun you are correct and he committed a felony.
Not that I wouldn’t like to see that slimy fascist frog marched into a cell but I think that our little discussion here serves more to point out assinine gun laws rather than the criminality of leftists.
I have purchased firearms as presents, but I defy you to purchase one being honest about it. Dealers are extremely gun shy (hmmm) about anything that faintly smells like a straw purchase.
While in Phoenix I bought a shotgun for my son, to do so, we had to fill out the forms in his name, so that the sale was officially to him. I simply paid for it.
