Premium Titanium Performance

The Altra Phantom Titanium Outsert is engineered for archers seeking the ultimate combination of strength, precision, and performance. Manufactured from Ti5 titanium, these outserts offer exceptional durability while increasing front-end weight to support advanced arrow tuning and FOC optimization.

When paired with the ARCOS insert system, the insert secures 0.875 inches into the shaft while the titanium outsert encapsulates 0.43 inches of the arrow's leading edge. This dual-component design helps reinforce the front of the shaft and creates outstanding structural integrity.

Integrated O-rings within the ARCOS system help secure the outsert, reduce vibration, and improve concentric alignment between components. The result is a more consistent arrow build with improved downrange accuracy and performance.
