Carbon Tube - Sigalsub
The Sigalsub Carbon Tube is the original replacement barrel for 100% carbon fiber spearguns, designed and manufactured in Italy to ensure maximum performance in spearfishing. Compatible with the Nemesis speargun range and with the main Sigalsub components, this tube is the ideal choice for anyone looking to build a high-performance custom gun or replace the original barrel while maintaining the brand’s quality standards.
Construction and Materials
The barrel is made from high-modulus carbon fiber with a wall thickness of 2.0 mm, ensuring the perfect balance of light weight, structural rigidity, and pressure resistance in the marine environment. The outer surface is not screen-printed, leaving full freedom for custom personalization.
- Material: 100% high-modulus carbon fiber
- Wall thickness: 2.0 mm
- Outer diameter: Ø 30 mm
- Inner diameter: Ø 26 mm
- Outer surface: not screen-printed
Integrated Shaft Guide
The shaft guide is integrated and is structurally part of the barrel itself: it is not glued on or applied afterward. This construction solution significantly increases the barrel’s rigidity, especially in the vertical direction — the one most stressed during the shot — ensuring precise and consistent trajectories over time.
Configuration and Accessories
The tube is supplied without watertight plugs and without mounting holes for muzzle and handle, allowing it to adapt to a wide variety of rigging configurations. The black nylon fastening pins Ø 4.0 x 30 mm are included as standard and are also available separately as a replacement part.
- Watertight plugs NOT included (available separately)

Nemesis Closed Muzzle - Sigalsub
The Sigalsub closed muzzle for Nemesis spearguns is the dedicated component for hole hunting and short, powerful shots. Designed and manufactured entirely in Italy by Sigalsub, this muzzle transforms the Nemesis speargun into the ideal configuration for tight environments, crevices, and close-range hunting with maximum efficiency.
Technical Features
- Closed Muzzle with threaded holes for parallel in-line bands
- Screw-in Bands (with bushings) for a compact, powerful setup
- Made from 30% fiberglass-reinforced nylon, the same high-strength material used for the Nemesis handle
- Compatible with threaded shafts for mounting a prong or spear tip
- Compact design, among the smallest in the spearfishing speargun category
- Quick assembly via transverse locking pin, a proven system used throughout the Nemesis line
- Watertight seal ensured by dual O-rings on the male insert
- Compatible with Nemesis aluminum barrels (6082 alloy, 28 mm outer diameter with integrated shaft guide)
Why Choose the Closed Muzzle Configuration
The closed muzzle is the optimal technical solution for hole hunting: the in-line bands with bushings deliver concentrated, direct thrust, ideal for short-range shots where immediate power is required. The closed geometry protects the bands from impacts against walls and rocks while maneuvering in confined spaces, increasing component life and operational safety.
Nemesis Versatility and Customization
One of the strengths of the entire Nemesis system is its modularity: by replacing only the muzzle, you can convert your speargun from an open circular-band configuration to a closed configuration — or vice versa — without modifying the handle, barrel, or trigger mechanism. This makes the Nemesis closed muzzle a versatile investment, allowing the same speargun to adapt to different spearfishing techniques.
Italian Sigalsub Production
Sigalsub is an Italian artisan company that combines precision machining with manual finishing and assembly, with quality control on every single component. Sigalsub’s expertise in trigger mechanisms and speargun components is recognized internationally, which is why many professional spearfishers choose Sigalsub components for building custom spearguns as well.
Accessories and Spare Parts for Spearguns
In the context of spearfishing, a speargun is often not a single monolithic piece of equipment. It is a set of modular components that can be replaced, upgraded, or customized. Handles, muzzles, grips, line guides, loading pads, and small hardware are elements that directly affect the configuration of the speargun.
This section includes accessories and spare parts for spearguns designed for spearfishing.
Product types
Handles for spearguns
The handle is a fundamental component of any speargun. It is the main interface between the spearo and the gun. This category includes complete handles, sold as ready-to-install kits, as well as modular handles whose body, internal insert, external grip, and loading pad can be purchased separately.
The available handles include models with ergonomic geometries developed to ensure a stable grip even when wearing neoprene gloves. The availability of brackets and loading pads as separate accessories allows the speargun to be further customized.
Muzzles for spearguns
The muzzle is the front component of the speargun that holds the shaft in the loaded position and accommodates the bands. This section includes muzzles in open (open on top) and closed (equipped with an upper locking system) formats, with configurations for a single circular band, multiple bands, or inline bands.
Grips, inserts, and spare parts for handles
In addition to complete kits, the category includes individual spare components: rubber-like grips for the outer handle grip, internal inserts that house the release mechanism, rubber butt covers to protect the rear part of the handle, and handle bodies sold separately. These products make it possible to restore or modify the functionality of an existing handle without having to replace the entire assembly.
Line guides and line retainers
Line guides are small components mounted on the speargun barrel to guide the line connected to the shaft, reducing friction and keeping the line or monofilament in the correct position during the shot.
Accessories and small hardware
The range is completed by accessory components, including the plug barrel, an end cap for cylindrical spearguns that prevents water from entering the barrel.
Practical use
Accessories and spare parts for spearguns are used in two main distinct scenarios: routine and major maintenance of the speargun and customization or assembly of custom guns.
For maintenance, spare components are used to restore functionality. For customization, components are selected based on the functional characteristics of the custom speargun.
A typical example is replacing the original handle with a model featuring a different geometry or an integrated loading pad. Another example is switching from a closed muzzle to an open muzzle (and vice versa).
Proper installation of the components often requires checking component compatibility.
