Designed to produce the enormous entry and exit wounds required for extreme blood trails, the Rage X-Treme 4-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-INCHES this head delivers extreme blood trails. The .030" thick single-piece, 7/8" cut-on-contact tip and two double-bevel .035" expandable wing blades that span 2.3-inches 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 4-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.
