Rage HypoDermic NC 100gr Expandable Broadheads - 3 Pack - The revolutionary Hypodermic NC utilizes cutting-edge finger-like tabs on the blades' Slip Cam pivot point to "anchor" them in place while in the closed position, completely eliminating the need for a SHOCK COLLAR, dental band or O-ring, while still providing reliable blade retention. Upon impact, the blades instantly deploy to a 2-inch cutting diameter, administering the gaping wounds that bowhunters have come to expect from the field-proven Rage Hypodermic series. The new 100-grain Hypodermic NC features the lethal Hypodermic hybrid tip with an even narrower profile and needle-like ferrule. In flight, that streamlined design makes for superior field-tip accuracy. The two .035in thick blades deploy on impact, sliding into a swept-back blade angle while the monstrous 2in cutting diameter delivers a wide entry hole for gruesome blood trails and brief tracking jobs.
