DefendAR-15 AR-15 Bump Fire Stock
Fostech Outdoors are about to ship the DefendAR-15 bump fire stock for the AR-15. It is selling for $500.
It works just like the other bump fire stocks on the market: the rifle sits in the stock but is free to move backwards and forwards, the operator then pushes the rifle forward forcing the trigger against their trigger finger, the recoil of the fired round pushes the rifles back reseting the trigger, the operator’s continued forward pressure restarts the cycle. Repeat until out of ammunition.

The first time some idiot goes on a shooting spree with one or shoots at the police with it they will be outlawed.
This looks much better built than the Slide Fire. Only thing is the Slide Fire is easier to install with fewer parts. Hard to say which one is really better.
