Have you ever tried the slide fire stock (as pictured there on the rifle in Hickok’s hand) on an AR or AK?
Thinkin seriously about spending the 300 bucks

The slidefire stock works like a hose on the AR 15.
It works on the AK47 but muzzle rise is an issue.
I think it would work great on an AK74 but have not tried it.
