Engineered for Precision and Strength

The Altra Centrum Titanium Outsert enhances the ARCOS platform by combining premium titanium construction with a highly engineered concentric design. The ARCOS insert secures deep inside the shaft at 0.875 inches while the titanium outsert encapsulates 0.43 inches of the shaft's leading edge, creating a reinforced front-end system built to withstand demanding conditions.

Integrated rubber O-rings within the ARCOS system help secure the outsert in place while reducing vibration and improving alignment between components. This results in a more concentric arrow setup that promotes greater consistency and accuracy downrange.

Manufactured from high-strength Ti5 titanium, these outserts provide the added resilience and weight many archers desire when building premium hunting arrows or high-performance target setups.
