I see. If the recess isn't milled out deep enough you definitely aren't going to be able to force the recoil lug deeper with a hammer. I recall when stockys was on the shoot2hunt podcast they said the material used for the inlet area has a much higher strength than aluminum when it comes to crush force.Looks like that isn’t going to possible with his stock. It’s the one that arrived unseated and too high to bolt up the action.
