Sorry it took so long man.
So i use the triclawps on the front as you can see. Then on the back end i use a primos trigger stick, ill take a beannie inside a beanie or whatever we have on hand and put it in the cradle of the trigger stick and use the cord to hold it in place, the thicker the better which allows you to get a real good cheek weld. Its gotta be the trigger stick though, it allows you to instantly adjust the back end just by squeezing it. Rock solid set up, takes some getting used to but works great if laying prone isnt an option.
