Did you have to change the front sight to?I don't know about $80...but the Williams 5D is about $35 at Midway and certainly worth the money. I have one on a Win. 94 and another on a Marlin 336. For use on a short barrel Trapper it should be just fine out to 100yds or so.
I think with the 16" shorter barrel a taller front sight is neededI think I need a taller front sight for mine as well.
