Interesting, not a full auto but almost the same effect

IMHO, it seems like a waste of $$ to spend $150+ for a stock that allows you to fire $$$ ammo at a crazy rate of speed and not gain any accuracy. Sure, with enough practice you may get good with it. It's just not a "normal" thing to lock your trigger finger and shooting hand stationary,then pull your rifle "away" from you.

In any tactical situation, my focus is on getting sights on target and managing recoil. The trigger finger already knows what to do. This is totally ass-backwards. Still, it's a fun toy and makes for great entertainment. I'm just not looking to waste ammo or money.

Yeah it didnt seem very accurate

But a 22 version of that might be a fun toy!

I guess. If you installed it on an AR-22. I wonder if there is enough recoil to make it work?
