So, I'm a WA resident that has just moved to AZ. Thinking that since I could buy long guns while down here I ordered my AR receiver before I changed my residency. Turns out that I can buy a rifle but not a rifle receiver. WTF is that about? It's not a big deal I guess, I think I'll have time to go and get my license switched over tomorrow. Still a bummer since it was that last part I needed.
I really am starting to dislike the ATF lately...

ATF changed the rules about 2 years ago on receivers, because they could be made into a pistol.
1) An FFL may not sell a frame or receiver to anyone under 21 years of age [Title 18, U.S.C., section 922 (b)(1)]. Comment: This is because the receiver could, potentially, be made into a pistol.
2) An FFL may not transfer a frame or receiver to an unlicensed person from another State. [Title 18, U.S.C. section 922(b)(3)]. Comment: Again, this tracks the rules regarding transfers of pistols, because some frames/receivers can be built into pistols.
