The revolutionary Rage 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 .035? thick blades deploy on impact sliding into a swept-back blade angle while the monstrous 2? cutting diameter delivers a wide entry hole for gruesome blood trails and brief tracking jobs.2-Blade Broadhead100 GrainHybrid Hypodermic TipMachined Stainless Steel Ferrule035" Blades2" Cutting DiameterNo Collar Blade LockReplacement Blades SKU: R381053 per Package
