If you haven’t bought the stinger yet, get Caldwell’s precidion turret rest instead. Will work great with standard rifle configuration and bullpup/AR style guns, and doubles as a gun service maintenance tool because of the vise clamp feature.
Nothing wrong with the stinger as I own both, just don’t walk away from your gun while on the stinger without slapping a bungee cord to hold the gun down. Your gun can easily tilt off the rest
