Take Leading Edge DNA from Tremor & Hypershock, add steroids, attitude and a few more knives for good measure!  The new Xbow XPR™ takes Aftershock's award winning patent pending design to new levels. First, they engineered a new shorter ferrule with even higher mass-centralization than the industry leading Hypershock and Tremor. Then they designed the new XPR blades with a new super-efficient shape and added new Cut-On-Contact rear deployment blades that create a devastating entry wound channel.  As with all Aftershock broadheads, the Xbow XPR™ has the exclusive "Physics" based inboard Center-of-Gravity blade geometry. This means the Xbow XPR™ blades physically cannot open on release - but will open in game every time! For accuracy and a devastating Speed-Kill with today's fast Crossbows, the Xbow XPR™ becomes a necessity.
