I have to disagree with ColoradoElk. I just bought an A-bolt comp stalker in .338 this past December and the Boss ADDS to the value (although I know he dosen' t like ' em) I researched prices on this rifle and the models with the boss go for +- $600 and the models w/o the boss go for about $80 less. What to offer is up to you, just remember, it is an almost new rifle...I would probably start at $400!
