What...? When did importation of those parts get banned by arms embargo? Probably all that stuff is for or can be used by the airsoft community and now between airsoft product designers and manufacturers basically, building airsoft stuff modeled after actual firearms stuff, the intermix between products from them can be used for both which is what I presume is happening now. More than a few times, I've purchased pretty decent picatinny rail covers, high drain batteries, etc from Chinese manufacturers and there's quite a bit of US retailers that get their products made and/or CNC'ed and imported in from China. Kinda confusing with the inconsistency and nitpicking by BP.
