The guy ought to know that since we're identifying and describing guns used in films, we're gonna notice things like incorrect stances and what attachments are on an extra's pistol or long gun. It's not ridiculous, it's called
an eye for detail and it's not something I'm gonna be ashamed of because of some anonymous Internet critic.
Also, the screencap from
xXx of Gold Tooth with the AKM... even I'm dumbfounded as to what that means...
And what exactly would linking to a gun on eBay source anyway? That eBay allows gun sales? That eBay is a secretly militant organization arming its operatives?
