I understand some Chinese stuff may be sub-par, but my main interest was that they seized stuff like stocks, sights, etc. - not the functional parts of firearms. Maybe I don't want the Chinese knockoff of a magpul stock, but if I did, seems like that shouldn't be any of the gov's business.
I worry when something like this arms embargo just globally encompasses stuff. I worry about what the anti-gun politicians can do with such wide-ranging powers regarding what the functional parts of a firearm are.
