I've been looking to replace an old tm compatible px4's tinted receiver for a while but never got around doing it purely because nobody's really had an answer outside of saying customs would seize it if it already had all the internals in it. But would the bare receiver itself be legal to import? (this one's out of stock, but it's just a gutted lower receiver)
