Fast Trigger

[Which Way Out]

Here's one. Years ago I saw someone with a device that attached to the Trigger guard of his 10-22. It filled the finger space and had a handle that you cranked like an old pencil sharpener. Not sure if it trigger the gun at 1 RPM or more, but it was cool. He could unload a 30 rd mag in no time.
Anyone ever seen or heard of these ?
And before everyone gets all crazy about it being illegal, lets not go there, we already know that don't we.

You get a gold star..
So, is it legal ?
My guess is NOT

Lame device.

Illegal in CA.

I think i can bump fire faster then the trigger wheel. But interesting to see. Use crap ammo and you'll get FTF, renders that trigger wheel useless.
