Designed to produce the enormous entry and exit wounds required for extreme blood trails, the Rage X-Treme four blade leaves nothing to chance. Combining a streamlined black anodize aircraft-grade aluminum ferrule with fixed and movable blades to deliver total cutting surfaces in excess of over 3.1 in this head delivers extreme blood trails. The 0.03 in thick single-piece, 7/8 in cut-on-contact tip and two double-bevel 0.035 in expandable wing blades that span 2.3 in across administer massive tissue damage for better blood trails and quicker kills, with exceptional penetration and durability. Like all Rage broadheads, the new X-Treme four blade features Rage's exclusive Slip Cam technology for reliable blade deployment and SHOCK Collar blade retention system for dependable blade containment prior to impact. Each pack of two broadheads includes a second set of red high energy SHOCK Collars to meet the demands of today's highest energy bows and crossbows.
