I said if u get lucky...u may fail a 30->40h 3-4 times before you get it. Ur not gonna get 40pd for a 40h Bringers. It took me 6 tries to get from 40-50...u think Imma get 80pds for a 50h Bringers rifle? Probably not.
18 pds seems pretty low given that it would take you 23 pds counting the cost of the arm to make if you lucked out every time and this is a weapon with decent demand. Anyone aiming for a 50 hitter would take that deal. I would put it more in the range of the high 20s low 30s personally.
