Did yall just go all fratty on us? Anyway, I have a buddy that has one of those stocks and if you don't believe me, just hang out with him and he'll tell you about it every time he sees you.
Anyone who dabbles in NFA weaponry has a sizable amount of money to toss around. She's holding about 15-25K. Although, it appears to be a newer firearm. In which case, it's not eligible for civilian ownership and belongs to either a Class III manufacturer or a law enforcement agency which has given her the hookup. If it weren't for government overreach, NFA items wouldn't bring such inflated prices. The government's "gone wild" approach has transformed $1,000 firearms into $15,000-$25,000 firearms. A circa 1986 M16 wouldn't bring hardly anything if it weren't for the ban. And my rant ends. My post above is incorrect. I took the video's title in good faith. When you click the link, th video info points out that it's a standard semi-auto with a sliding stock. The title is deceiving. It's not a legal machine gun. That's the best bump fire that I've seen. Not long ago, BATF went on one of its standard witch hunts and seized a newly developed trigger mechanism and demanded that all the purchasers of the device turn theirs over.
Please excuse me if I am out of the loop. I read up on the slide fire stock. It's a stock than can be added to most AR and AK platforms. It appears to actually work, unlike most other gimmicky trigger devices, excluding the one that was swept up by BATF.
