You don’t need to have this attachment to speed trigger action. A simple belt loop can do the same thing. This is just a catch phrase that the idiot media and Democrats have latched on to beat up the NRA. It was Obama’s ATF that approved the bump stock, and Republicans ought to repeat that every time it’s brought up.

While it is true that you can do primitive bump fire by hooking your belt loop, it is very unstable and inaccurate. Reloading is more cumbersome as well.

A bump stock attached to a weapon enables tripod or bipod mounting, and much more stable and accurate high rates of fire.

" You don’t need to have this attachment to speed trigger action. A simple belt loop can do the same thing."

Yes. (At least I'm willing to take your word for it. I have no experience in this area myself.)

And illegal enough to get a person sent to federal prison.

You don’t even need that. Some people that have been avid video game players their entire lives can actually legitimately pull the trigger on a semi-auto fast enough to achieve a 400-600 round per minute fire rate. Not even bump firing, they’re just that fast.

And there are older non-gamer people who are just as fast. Jerry Miculek, for example. True, he’s using a specially prepped race revolver with a light trigger - but he has to be able to pull that trigger repeatedly. He had a 480 round per minute fire rate... On a double action revolver.
