The brass piece you see is part of an internally expanding 2-piece "clamp" set. You should be able to loosen it by sliding the outer bolt through the brass piece and engaging the threads on the inner piece. Give it a light tap, and it should all loosen enough to be gently slid out.
As Popgun and Cormanus have shown above, there are quite a few pieces to the stock bar end - it bolts to a rubber-mounted weight that has clips that hold it into the bar.
