I wasn't trying to grill you--it was for my information. I have that peeve also, but am obviously less knowledgeable than you. Thanks.
Er...
It's 'thumb hole', not butt hole. For once, not due to PC.
Fact of the matter is that
(a) Recent feel good laws apply more to looks than function. However, since they seem to change in interpretation almost monthly, I for one am never quite sure what remains legal and what has been morphed into evil.
(b)Previous anti-atuomatic [and explosives] laws applied to function and the fact that joe average could - and was encouraged to - buy a Tommy Gun after WWI.
those old laws are entirely sufficient & some of us believe it should be cheaper and easier to possess a full auto.
(c) MSM always states "AK47", which is full or simi auto and not legal, when showing someone with a civil version, which is semi-auto by definition.
(d)MSM then generally slips to a different scene, another time, showing someone else shooting anything in full auto - sometimes at a legal pay-to-play event or just file footage of bad guys pretending to be proficient with the real thing.
(e) "Automatic" in general use typically means anything that loads anothe round as a result of firing the previous round; it loads but does not shoot that round. Better to use 'semi-automatic' for self loading, user initiated, versus 'full-automatic' for something that fires 'em off as long as the trigger is held down - such as an AK47 or proper M-16. But remember that even these time honored relics are capable of both semi and full auto fire, it is the capability that is illegal.
