In state, out of state, doesn't matter if it's for repairs, not sales.
Like my rifle I mailed to Kentucky or wherever the hell it is lmao. They'll mail it right back to my house.
I passed up a NOS one for $12. My buddy set aside a bunch of mags for me at the shop and that one was in there. He wanted it so I let him buy it bc I wouldn't have even got any of the others if it wasn't for him. But that mag looked unissued.
