Here’s a photo of the all-new Kill Zone broadhead from New Archery Products.
This is an interesting mechanical head. The rear-deploying blades are held in place during flight by a built-in spring clip that requires roughly 3 pounds of force to open. Upon impact, the blades deploy to a 2-inch cutting diameter.
The Kill Zone is a 100-grain head available for both standard inserts and the new Easton Deep Six insert system.
