I love my bighorn eventhough I missed a 130 yard shot on Sunday. Shot right over it, the classic holding too high on a steep downhill shot. Anyway, I got mine last spring, thumbhole stock, what I did was I bought the Williams peep and a red front optic sight instead of the green one it comes with.Being a geezer like MRay

my eyes melted the rear reds with the front green to a fine blurry line. The peep is awesome and I much prefer the red over the green front it comes with.
