recoiling stocks?

[hardstalk]

A friend of mine has a 300 rum. And the stock recoils into itself. I'm building my wife a rifle and would like to add this to it. Does anyone know of a manufacturer that makes these? I want to say it was behind where the cheek would rest and the stock has a spring inside to reduce recoil.

Blackhawk Tactical sells the Knox stocks system in both a stock and as an aftermarket add on.

I think the recoil system is actually built by Knox not Blackhawk.

Google will tell you.
