The Viper Venom is spin stabilized using variable degree axial flow airfoils.  These patented airfoils, called Spin Tite Airfoil Technology enable the VIPER VENOM to fly like mechanicals yet with all the knockdown power of fixed-blade broadheads.

Viper Venom cut-on-contact broadheads offer unsurpassed penetration while featuring the patent-pending Spiral Wound Channel that cannot close or clot insuring massive hemorrhaging and unmistakable blood trails.  The result is incredibly rapid bleed-out leading to quick and humane harvests.
