I lucked out with my laminate stock.. there is no play at all. I set the stock on and start the back locking lug first, sending that in half way. Then I start the front locking lug and tighten that but not completly. I then tighten the back lug tight and then finish with the front. Also I never crank them into place. They are tight mind you but I am not going to bend the wrench to do so....
