Cuttlefish Carbon Fiber Speargun Barrel
Price range: 56.00 $ through 73.00 $
Our cuttlefish carbon fiber speargun barrel combines a standard round carbon fiber tube with streamlined side wings. This profile creates the recognizable cuttlefish shape while keeping the front and rear connection areas compatible with the required speargun components.
An integrated rail runs along the top of the barrel to guide the spear shaft. The carbon fiber structure offers low weight, high stiffness and good resistance to the marine environment.
We manufacture barrels according to your required length, cross-section, connection dimensions and surface finish.

Why Use Cuttlefish Carbon fiber Speargun Barrel?
Increased Bending Stiffness
The wider middle section can increase structural stiffness compared with a basic round barrel of similar length.
Higher stiffness helps the barrel resist bending under band load and supports consistent shaft alignment.
Improved Buoyancy
The larger middle profile provides more internal volume. This can help manufacturers adjust the balance and buoyancy of the complete speargun.
Final buoyancy depends on the barrel dimensions, wall structure, sealing system, shaft, reel, handle, muzzle, and other assembled parts.
Better Underwater Balance
The position and size of the side wings can be designed to improve weight distribution and handling.
A properly balanced speargun may require less effort to hold and aim underwater.
Hydrodynamic Shape
The tapered wing profile creates a smooth transition between the narrow ends and wider middle body.
The exact underwater handling depends on the final profile, width, length, and complete speargun configuration.
Premium Product Positioning
The wide carbon fiber body and visible 3K weave give the complete speargun a distinctive, high-end appearance.

Frequently Asked Questions
1. Is the entire barrel flat or wing-shaped?
No. A continuous round tube runs through the entire barrel. The streamlined wings are added only along the middle section.
2. Are both ends round?
Yes. The side wings taper away before the ends, leaving round tube sections for handle and muzzle installation.
3. Does the shaft guide run across the whole barrel?
Yes. The integrated guide runs continuously along the top of the round tube and through the winged middle section.
4. Can the wing profile be customized?
Yes. Wing width, length, thickness, taper, and position can be developed according to the customer’s project.
5. Do you sell single replacement barrels?
Our primary service is B2B and OEM manufacturing. Sample quantities can be discussed for product development and approval.

Custom Carbon Fiber LED Display Frame
Our custom carbon fiber LED display frames provide a lightweight and rigid structural solution for modular LED cabinets.
Compared with conventional metal structures, a properly designed carbon fiber frame can reduce cabinet weight while maintaining the stiffness required for accurate screen alignment. Lower structural weight can help reduce transportation costs, truss loads, and installation effort.
Each frame can be developed around the customer’s LED module arrangement, cabinet dimensions, locking system, mounting points, and service requirements. (Frame body only. LED modules, power supplies, control systems, and display electronics are not included unless otherwise agreed.)
Custom Carbon Fiber Luggage
Our carbon fiber luggage combines real composite panels with a strong framed structure. The visible woven surface gives the suitcase a technical and premium appearance, while the surrounding frame protects the panel edges and supports the hardware.
The pictured model uses woven carbon fiber panels, a dark metal frame, reinforced corners, a telescopic handle and four spinner wheels. Its structure, dimensions and accessories can be adjusted for OEM and private-label projects.
This product is suitable for brands looking for luggage that stands apart from common plastic or aluminum-shell designs.
Round Carbon Fiber Speargun Barrel
ANT Composites manufactures round carbon fiber speargun barrels for spearfishing equipment, replacement barrels, and OEM speargun projects.
The barrel uses a continuous round carbon fiber tube as its main structure. Two low raised shoulders run along the top and form a shallow guide track for the spear shaft. This integrated design helps keep the shaft aligned without adding a separate external rail.
Standard and custom diameters, lengths, wall thicknesses, carbon finishes, and guide profiles are available.
