I have a .12 gauge version and your right kicks like an army mule. Although I have an old sears bolt action .12 that kicks harder.
My buddy has a .20 gauge version I would like to have if he ever sells it.
I’ve got a set of them, both by J C Riggins, the Sears brand. One is a 16 gauge with a choke and the other is a 20 gauge. Both bolt actions. Freepmail me if you’re interested.
The stock on the 20 is cracked but it’s still functional.
