Long time lurker, here, posting my first diary in several years. I haven't felt the need to add anything to the conversation here for such a long time, you guys do such an amazing job. However, recently, a few diaries were posted linking to a youtube video on "bump firing", and though this concept really makes the case against high capacity clips by itself, there is a new development that isn't getting much attention: the fact that simply adding a (legal) modified stock to any semi-automatic rifle can effectively turn it into a machine gun.
The link is here...
Bump Fire Black Rifle vs Machine Gun
The description of the (very simple) principle is at 3:05, and the demonstration starts at about 8:40.
I hope we start talking about this again.
