I ordered mine on 04/01 (Featherweight Thumbhole/Pepper) for my Axis .308 and didn't notice till last week that it's doing the same thing. No matter how hard I tap or even with the bolt removed, it will not seat and lock in place. I tried calling Boyds today a little after 9:00am CDT and got a recording stating the "Business Hours". I have to say, I'm a bit disappointed.
