NAP Technology

Mechanical Broadheads


The DK4 represents the next level in broadhead development. This hybrid-mechanical broadhead features a pivoting main blade and two mechanical bleeder blades designed for maximum penetration potential. The main blade hit hard and deflects around very thick bone sections to maintain momentum and deliver true pass-through power. Spitfire spring clip technology holds the main blade in during launch and the bleed blades are guaranteed to open on impact no matter what your target.


2” Cutting Diameter

The massive 2” cutting diameter creates a devastating entry and exit wounds for quicker recoveries.

No O-Rings or Rubber Bands

NAP’s spring-clip design holds your blades closed in your quiver and flight, every time.

Cut-On-Contact Tip

The Killzone® is available with a cut-on-contact razor tip for extreme cutting and penetration.

Trophy Tip

The Killzone® is also available with a Trophy Tip, which offers the bone-crunching toughness many bowhunters demand.


The Deep Six Spitfire Maxx is a 3-blade mechanical broadhead that makes huge cuts. With a 1 ¾” cutting diameter and new “over-bore” technology, the D6 Spitfire Maxx penetrates deeper for maximum devastation. The new longer Trophy Tip allows the broadhead to penetrate deeper into the target before the blades deploy, which further reduces the chance of deflection even on the steepest angles.

Deep 6 broadheads are designed specifically for Easton’s line of Deep 6 arrows. Like the standard Spitfire Maxx, the Deep 6 Spitfire features ultra-sharp, rugged blades as well as NAP’s legendary blade retention system. No o-rings or rubber bands are needed.
