Originally posted by JMG: I believe Zwickey only makes one their broadheads with the screw in adaptor in the weight that you're looking for, "Eskilite broadhead". The Eskilite broadhead is around 110 grains without the screw in adaptor glued on. They are 2 and 4 blade, and both weigh 135 grains. But check with 3 River's website to make sure what I said was right. Good luck and happy hunting!!
Originally posted by Steve Jr: They also have the No-Mercy heads in a 130 screw in. Kustom King sells them also $17.25 for a 3 pack. Eskilite is 135 grain and $16.60 for a 3 pack. Good luck this season.
