Contact148 - the interpretation of what is the receiver is only relevant if original parts are used. If the main casing w/trigger housing and magazine housing were both newly made, and if the mechanism were seriously semi auto, then there shouldn't be a problem. Unlike some other designs, the Sten is not specifically named, so there is no "or variant of" situation. A completely new gun would be just another semi auto firearm, with restricted or non-restricted status depending on barrel length.
