The Spartan was developed from taking the best characteristics from larger 19/64” and smaller 17/64” arrows. We wanted the Spartan’s outside diameter to be small for maximum accuracy and penetration. However, like larger arrows, we wanted the 100% carbon Spartan to utilize an insert for easier arrow removal and to reinforce the front of the arrow for bone-shattering impacts.

I shot carbon express for many years , but they discontinued the blurbs so I thought I would give these a try . Wish I had started out with these awesome arrows. Very consistent, accurate arrows .Just won a three day tournament with my spartans , even shooting in the wind incredible .
