Coonan receivers are good. There's no way to know if it's an Imbel or any other parts kit, but it's built from some parts kit. If the parts are all metric, then it really doesn't matter. There were no "bad" makers of military FAL's, so regardless of which parts kit, the parts will be made well. At that price I'd probably take it even if it didn't work (anything on a FAL can be fixed).
