Carbon Express Mayhem Fletched Carbon Crossbolt 6-Pack - Tuned

In this review the Carbon Express Mayhem Fletched Carbon Crossbolt is judged as a purpose-built option for hunters and serious target shooters who need consistent, broadhead-ready performance from a crossbow bolt. The single biggest reason to buy is its focus on straightness and spine consistency, which translates into repeatable down-range accuracy and reliable penetration with a broadhead. The review covers construction, fitment, and the practical benefits of the included nocks and 3 in vanes, based entirely on the product's engineered features.

Key Features

• Multi-layer construction: Tuned for modern high-powered crossbows, the layered carbon shaft helps maintain accuracy and penetration at hunting ranges.
• Real straightness: Precision sorted to +/- 0.004 in for uniform flight and consistent group sizes shot after shot.
• K-360 weave technology: The back shaft integrates a carbon weave into the outer layer to improve spine consistency and long-term durability.
• Fletched with 3 in vanes: The Dragon 3 in vanes provide a stable, predictable trajectory for broadhead and field point setups.
• Complete nock options: Each 6-pack includes inserted moon nocks plus six universal flat nocks so shooters can pick the nock style that fits their rail system.

Who It's For

The Mayhem crossbolt is best for crossbow hunters and precision-minded shooters who need bolts that are tuned for high-speed modern crossbows and that perform consistently with broadheads. Its tight straightness tolerance and spine engineering make it suited to anyone pursuing clean ethical shots on game or dialing in consistent groups at range.

Those who should look elsewhere include casual plinkers who want the cheapest possible bolts, and archers who require specialty lengths or extremely light-weight shafts not represented by the 20 in, 420 grain Mayhem. If you need a different length or weight, consider shafts specifically matched to that requirement.

Pros & Cons

Pros

• High precision straightness (+/- 0.004 in) produces repeatable groups and less tuning time.
• Multi-layer carbon construction and K-360 weave add spine consistency and durability under high draw forces.
• Comes with both inserted moon nocks and six universal flat nocks for immediate compatibility with most rails.
• Fletched 3 in vanes stabilize broadheads for better down-range accuracy.

Cons

• Offered only in a 20 in, 420 grain configuration, so shooters needing other lengths or weights must look for alternatives.
