Just received my A5. The front screw bottoms out before the action is tight, like a 1/4 inch of slop. Does the eschusion need to be used? Mine got tossed when I put a pillar in my last stock. I got a new one coming along with a new screw. Two washers from the sling studs seem to work to shim it in place. Pics coming this weekend if I can get this whore together. May still put a dab of JB under the wedge
