I would ask to see another a-bolt, and see if it has the same slack, and also try loading it. I have a few Brownings, and that is not a trait found in any of them. I really would look at another rifle, you never know what some yahoos may have done to it while they were looking at that gun. Someone may have opened it and forced it back a little .... causing it to be " sprung ". Ask to see one out of the box. I bet the fit will be better.

God Bless
