The American-made NAP Spitfire Double Cross Broadhead uses failsafe blade retention technology to ensure blades never open in flight, even when using the fastest bows. The 100-gr. broadhead integrates four, no-fail blades with two-stage deployment upon impact no O-rings or rubber bands needed. It cuts vertically and horizontally, regardless of the angle of impact, for gaping entrance and exit wound channels and high-visibility blood trails. Stage-one blades (.030 thick) boast a massive 1-7/8 cutting diameter. Rear-deploying stage-two blades (.027 thick) have a 1-1/8 cutting diameter. That totals up to 3 overall cutting trauma. Trophy tip delivers bone-splitting penetration. Per 3. Made in USA. Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Mechanical Broadheads.
