Neptonics is excited to offer the newly redesigned MannySub Roller Power Head Kit, coveted as the best roller muzzle in the world with an extensive history of smashing some of the biggest fish on the smallest euro guns. Designed for 16mm and 18mm bands.



The MannySub Roller Power Head is available in black and comes with one adapter, three different types of dyneema lines for the installation, stainless fittings, and easy-to-follow rigging instructions. *Add rubber to complete your conversion.



The new design brings several improvements: one-piece 40% glass-filled nylon design, lightweight carbon-fiber side plates, built-in anchor point for a bungee line with a 2.5mm reel-line guide, as well as an easy and fast loading system. These refinements make the Roller Power Head the most popular conversion roller kit available in the market.

The bearings are lightweight and low-friction for maximum power transfer. Made from acetal, with encapsulated glass balls to stop sand and salt-water damage. By eliminating recoil and generating more than double the power for a given barrel length, a Roller Power Head offers greater accuracy, penetration, range, and maneuverability.

A speargun equipped with the Roller Power Head uses 100% of the barrel length to propel the spear. Pre-tensioned rubbers and a greater rubber-stretch yields significantly more power. Any Euro Speargun can be converted into a roller speargun with this system. Two wraps of shooting line are recommended when using 16mm and 18mm rubbers.

  • 26mm (Pathos, Mares, Cressi, Hammer Head)

  • 26.5mm (Rob Allen, JBL, Aimrite, Mako)
