Terra Firma Vertex 5mm Shafts

Terra Firma Vertex 5mm Shaft

Pack of 12

The Terra Firma Vertex is the tough end of the 5 mm lineup — a heavier GPI shaft engineered for reliability on hard-impact shots. Its dense carbon construction produces stable arrow flight while improving energy transfer downrange.

Paired with a stainless collar and alloy insert system, the Vertex reinforces the front of the shaft and supports higher FOC hunting builds. The .204" (5mm) internal diameter keeps component compatibility wide and allows strong helical fletching setups.

A dependable option for bowhunters prioritising penetration, bone impact strength and predictable broadhead flight.

• Heavier point weights / high FOC builds
