Kleinsub - Carbon Barrel

Kleinsub Carbon Barrel for DIY Speargun Projects

Upgrade your speargun with a 3K carbon barrel and experience a significant improvement in accuracy, stiffness and control underwater. A carbon barrel drastically reduces weight compared to aluminium or stainless steel barrels — without compromising strength. In fact, carbon increases stiffness, reducing barrel flex and improving shot accuracy, especially with powerful bands and longer shots.

Benefits:

• Ultra-light construction: Easier to manoeuvre and reduces fatigue on long dives.
• High stiffness: Minimizes barrel flex during firing and improves accuracy.
• Corrosion-free: Ideal for both salt and freshwater — no risk of rust.
• Improved balance: Lighter front-end allows faster and more precise aiming.

Specifications:

• Material: 100% 3K carbon fiber
• Dimensions: 30 x 26 mm
• Lengths: Available in multiple sizes (customizable to your speargun model)
• Compatibility: Fits most speargun brands
• Installation: Designed as a direct replacement for existing barrels

Perfect for spearos seeking top performance, superior control and reduced weight. A Kleinsub carbon barrel elevates your speargun to the next level — technically and in feel underwater.
