No, not more comfortable.The only thing a bump stock offers is a more comfortable way to aim and fire.
Allow? Alter? Yes it does and that's its only purpose. I could probably fine tune the rifle fitted with a BP to fire at a rate that woud equal older 'machine' guns or older full automatic rifles or 'guns'. 1srelluc probably could too.It does not in any way all the weapon to operate like a full automatic.
No! You're trying to suggest they have no purpose other than providing 'comfort'.Whether there is bump stock or not doesn't matter on a semi-auto gun, when you pull the trigger you only get one bullet fired.
You'll have to find out and get back to me on the exceptions allowed.I thought full automatic weapons were already outlawed. And I'm pretty sure the current SCOTUS is not going to change that.
And fwiw, these things are worthless for any use other than dreaming of killing more lib/cons whatever. Only dreaming but not actually carrying out an American's actual political task. Ya'all are better equipped with a standard civilian issue AR-15.
