Barrel Adapter - Sigalsub

The Sigalsub barrel adapter is an essential component for mounting Sigalsub roller muzzles — and other compatible components — on spearguns with a cylindrical barrel. Designed with the same craftsmanship that distinguishes all Sigalsub production, it ensures a precise, stable, and watertight fit between muzzle and barrel.

Two sizes for maximum compatibility

Sigalsub adapters are available in two distinct diameters, designed to cover most commercial spearguns on the market:

• Internal diameter 26.0 mm — compatible with Seac, Pathos, Salvimar, Cressi spearguns and other models with a 26 mm barrel
• Internal diameter 25.4 mm — compatible with Seatec, Omer spearguns and other models with a 25.4 mm barrel

Technical features

• Specific component for mounting Sigalsub roller muzzles on cylindrical barrels
• Available in two diameter versions: 26.0 mm and 25.4 mm
• System with double O-ring seals for reliable watertight sealing
• Precision construction, in line with Sigalsub quality standards
• Essential accessory for converting your band speargun to a roller setup

What it’s for

Sigalsub roller muzzles come standard with the 26.0 mm adapter. This separate adapter is required for spearguns with a 25.4 mm internal diameter barrel (e.g., Seatec, Omer), or as a replacement part. It lets you take full advantage of the roller muzzle’s performance — more powerful shots and greater band stretch — even on band spearguns with different geometries.

Muzzle 610 Roller Speargun - Sigalsub

The Sigalsub 610 Roller Speargun Muzzle is a high-performance component for band spearguns for spearfishing, designed to convert a classic band speargun into an efficient Roller Speargun system. Thanks to its roller block technology, it delivers greater shot power, increased range, and reduced recoil for the same barrel length.

Roller Speargun technology: more power, less recoil

The roller system uses a longer band stretch than a traditional setup, generating significantly higher speed and kinetic energy. The result is a more stable shot, with drastically reduced recoil and a sight line that is maintained more accurately even with high-tension bands. Ideal for challenging fish and long-range shots.

Technical features

• High-sliding roller blocks for maximum band travel smoothness
• Stainless steel stopper shaped for the shaft-locking nylon line passage
• Central body made of glass-fiber-reinforced plastic material for high mechanical strength
• Compatible with most 28 mm cylindrical barrels with external diameter available on the market
• Included: 26 mm adapter (compatible with Seac, Pathos, Salvimar, Cressi, etc.) with a double gasket system for a watertight seal — also available in a 25.4 mm version (Seatec, Omer, etc.)
• Side front line guide, usable on both the right and left side for maximum flexibility
• Band capacity up to 16.0 mm diameter
• Included: stainless steel pin for securing the bands and stainless steel hook for building the loading aid
• Available in military green and black versions

Compatibility and versatility

The Sigalsub 610 Roller Speargun Muzzle is designed to fit a wide range of commercial spearguns with tubular barrels, thanks to its interchangeable dual-adapter system.

Wishbone XL with Bushings - SigalSub

The SigalSub XL Wishbone with bushings is an articulated wishbone for spearguns, made entirely from AISI 316 stainless steel using 4 mm rod stock. Strong, precise, and designed to deliver maximum ballistic performance, it is the ideal choice for anyone using double- or triple-band spearguns.

Construction and Materials

Each wishbone is made from 4 mm AISI 316 Stainless Steel rod stock, hand-bent and shaped to form the engagement hook. A second bend on the arms brings the bands perfectly back in line after engagement on notches or pins. The terminal surfaces remain rounded, significantly reducing the risk of abrasion in the event of accidental release. The version with bushings includes dedicated threaded Derlin bushings (16 pitch), allowing direct use with bands with bushings.

Ballistic Performance

Thanks to its XL dimensions — 65 mm length, 51.3 mm width, and hole center distance of approximately 47 mm — this wishbone keeps the bands perfectly spaced and parallel during loading. This prevents the rubber bands from overlapping, eliminating unnecessary friction and energy loss during the shot, for a consistently clean and precise sight line.

Recommended Use

• Ideal on double- or triple-band spearguns, paired with a narrower wishbone (wire or classic style)
• Also compatible with single-band spearguns, making it easier to engage and slide the hands out
• Pairing with wishbones of different widths to keep the bands perfectly spaced and parallel
