The bump stock used in NV

Was originally presented to the FBI as an ada device to help someone with severe arthritis pull a trigger?
Does anyone who owns one meet that definition?

Edit here is the link:

http://www.cnn.com/2017/10/04/us/bump-stock-las-vegas-shooting/index.html

Also the story has been updated

In 2010, Texas-based Slide Fire pitched the device to federal regulators as a new way to assist people with disabilities to "bump fire" an AR-15 type rifle.
"Individuals that suffer from severe arthritis, partial paralysis, or other conditions that affect their ability to traditionally operate a firearm can now utilize the SSAR-15 and the muscular strength in their entire arm to active the firing mechanism," the manufacturer said on its website.

Sorry no link handy

Are you trying to say the ability to commit mass murder should be limited to those who aren't disabled? How discriminatory of you!

I had never heard of such. I now understand the principle, but I still don't see how it works with a scope. And the audio clip I heard sure sounded like automatic fire, albeit at a fairly slow cycle rate for a 5.56x45mm rifle. As far as being an ADA device, seems to me to provide an extreme hazard. If you cannot repeatedly pull the trigger, can you safely stop pulling the trigger?

Exactly
I just read a bunch of Republican Senators are contemplating joining a CA(?) Democrats bill to ban their sale. I can't remember where I saw it so no link.

It doesn't and is more suitable to open sights or a red dot cqb sight. I chose the bump stock video for obvious reasons.:D

Great video! But I must have missed the part about the bump stock . . . :D

Seriously, I cannot see how those are legal under current law. I wouldn't have believed it, but surely that is truly automatic fire and thus a highly illegal conversion.

Its that man vision getting in the way again.:D

Completely legal because it doesn't modify the lower receiver in any way.

Exactly again, does anyone own one for their stated purpose? Being able to help a person with severe arthritis or a partially paralyzed person shoot.

It's still one trigger pull per round fired, not truly automatic. That's why it's currently legal, same as this:


The bumpfie stock has a flange (for lack of a better term) that forces your finger away from the trigger as the rifle recoils. By continually pulling forward on the forestock, it makes your finger hit the trigger again immediately after the recoil. This happens fast enough to simulate automatic fire.

The flange is right behind the trigger here, with the stock in the position it would be at the end of the recoil.

ATF determines their classification as a firearm or not. The ATF has rejected other designs that essentially performed the same function... Most recently a motorized glove thingy.

AS for it truly being automatic fire... it isn't. Why? Because the ATF dictates what is and what isn't a firearm and whether they are full auto or not. Ironically, we probably don't need politicians to pass any new laws about these as I think the ATF can simply change their evaluation of the device and essentially make them illegal overnight.

Yea that caught my ear as well, the slow cycling, a full auto m16/m4 would be almost twice as fast.. line of thought was that it was some different automatic weapon or maybe the supression slowed it down that much.. also the time between shots sounded a bit asymmetrical, not something id expect from a 556 device, but again with supression - maybe. I had to lookup bump stock firing on youtube when it popped up in the news, never heard of it before.

I believe that the laws need to be rewritten using the cyclic rate as the metric that defines a weapon's status. There has to be a clear definition on the rate of fire between a semi-auto and a fully automatic weapon. In my mind a semi-auto should fire 1 round per second max without any way to legally fire any faster which would render the bump fire stock useless. This is a problem that needs to be engineered out by the gun makers and lawmakers should clarify their intent better.

Yeah after seeing these vids im pretty sure that bump stock will be illegal shortly. She even mentions "full auto baby". The mechanics are different, but the end result is pretty much the same. Rate of fire is all that really matters when talking about this stuff.

Yeah I grew up hunting, with guns in half the rooms in the house, and shooting about every type of firearm out there. I just don't see any practical reason something like a "bump stock" should exist. Arthritis slowing down your rate of fire? That's really the excuse they want to run with? Come on. There are reasonable regulations and concessions that can be made to take products like this off the street.

It's actually interesting to watch the congressional GOP digest the existence of bump stocks. Seems a lot of them had no idea they existed (or are at least claiming so). Not sure it's a given they escape regulation this time.

Tell you the truth, that is just insane to have something like that. I never even heard of such a thing. Hard to believe the ATF allowed it.

You can bump fire from your hip very easily with a belt loop.

Skip to 1:45

You can probably also use overalls or something like that to fire from shoulder. You can do quick bursts by just making your wrist and forearm rigid but eventually you'll be overcome without a loop of some sort.
