Hey guys. I read the rules of importing parts for airsoft. I know that you aren't allowed to import the lower receiver or lower frame of the gun because it has the serial number on it.
Will the same apply for upper receivers or slides that have the serial number on it? Such as the PX4 Custom or the PDI L96 upper receiver?
And would this work vice versa? Lowers that have no serial number on it?
Or am I completely off? Anything to clear up my confusion would be greatly appreciated.
Please be nice to me.
