This article is etremely inaccurate. BATF sets the definition of a "machine gun" and nowhere in this article was there a "machine gun". Just more inaccuracies and half-truths that the media puts out to the sheep.

Luigi, dahlin', why do you force me to comment on ignorance (the article, not you)?!?!?!?!?!?! The headline is misleading and sensationalistic...........dare I say, Liberal tactics. Did you read the story completely and fully? Do you understand how these guns work, and what a "machine gun" truly is? Even with this "retrofit", the semi-automatic rifle does NOT become a truly full automatic weapon or a "machine gun". Geez...................Even if you support new gun laws and restrictions on our 2nd amendment rights, at least get your knowledge and facts right!!!!!!!!

yo lervia...'out there?...comment on this one if you dare.

What the slide fire does, it turns your weapon from a semiauto to a non-fully auto weapon by allowing the trigger not to reset itself fully and only staying within the breakpoint thus allowing a faster ammo discharge. But, you are not pulling the trigger for each round, rather the forward motion applied from your arm on the forend and your finger slightly on the slide fire trigger guard allows that when a round is discharged, the motion itself chambers the next round and keeps firing, this is what makes it fire at a faster rate than semi-auto.

why would any regular person need such a weapon? i just don't get it.

When he demonstrates the slide fire, he holds the weapon the wrong way- of course it won't be accurate when you fire holding the gun sideways from your elbow- no one but a wanna be gangsta would fire like that. When he fires the auto version, he holds the weapon properly (against his shoulder)- of course it will be more accurate.

Really poor reporting. The slide fire retrofit DOES NOT turn a semi-automatic weapon into a machine gun. In order to fire such a modified weapon the trigger has to be pulled to fire each individual round. The retrofit merely allows a user to fire the weapon faster, but it does not convert the weapon into a fully automatic weapon.
