It is the frame or receiver of the weapon that is a controlled item. You can't technically import those items either, so you're still fucked. Nice try though, but it's been tried before.
Now, you can buy guns here, just like you can buy metal bodies, etc. here. But that has no bearing on importation regulations. Check with a retailer and find out.

Democracy is two wolves and a sheep discussing what's for dinner.
Freedom is the wolves limping away while the sheep reloads.
Never confuse freedom with democracy.
