yes it is lead, or, in the case of a brass nut it is an iron bar.
it ensures as a counterweight that the nut reverses in the ideal position. (After each shot the nut rotates fast around.)
in the neutral position, the nut can be fixed by the bows internal mechanism while the string stretched can be attached behind the nut again.
