Single Roller Speargun Muzzle Kit - Ceramic

Single Roller Power Head Muzzle Kit - Ceramic

The Premium roller conversion kit Single Roller Power Head - Ceramic, made in Australia, is designed for installation on spearguns with a removable cylindrical muzzle. This system significantly improves power and accuracy in spearfishing, delivering greater penetration and range with superior control.

Main Technical Features

• High-speed ceramic bearings: four bearings (two per pulley) made from ceramic material with encapsulated balls, designed to reduce friction and increase power-transfer efficiency. Resistant to sand and saltwater, virtually maintenance-free. They are covered by a lifetime warranty.
• High-performance small-ID bands: 15, 16, or 18 mm bands with a 1 mm inner-diameter hole, offering high elastic performance to optimize pretension and maximize shaft thrust.
• Wraparound carbon fiber side plates: 2 mm thick, ultra-lightweight and strong, fully protecting the pulleys and bearings from impacts while improving the kit’s mechanical strength without adding weight.
• Molded one-piece body: solid and lightweight structure, designed for superior durability and balanced trim when swinging the speargun.
• Integrated line guide: allows the muzzle shock absorber to be secured and accommodates lines up to 2.5 mm thick, for versatile and safe installation.
• Complete with three types of Dyneema line: to choose the most effective setup based on your spearfishing needs.
• Rocker tie and barrel adapter: available for diameters from 24.5 to 26.5 mm, for compatibility with various speargun models.

Technical and Functional Benefits

The Roller Speargun system eliminates the recoil typical of traditional muzzles and uses 100% of the barrel length to propel the shaft, increasing power without increasing the freediver’s effort. By optimizing the ratio between band stretch and shaft weight, the kit generates more effective thrust, improving accuracy, shaft penetration, and handling of the speargun while freediving.

The lightness of carbon fiber and the low mechanical resistance of the ceramic bearings contribute to superior smoothness and responsiveness when shooting. Its simple construction makes assembly easy and ensures long-lasting reliability over time.

Compatibility and Usage Tips

• The kit is recommended for spearguns from 70 to 110 cm in length, but it can also be used effectively on 120 to 130 cm spearguns by installing 16 or 18 mm bands.
• Compatible with most Euro and South African spearguns with a removable cylindrical muzzle.
• Assembly instructions included to ensure correct and safe installation.
