CONVERT YOUR OLD RAILGUN INTO AN AWESOME ROLLER GUN! Superior power from a shorter gun makes manouvreing through the water a lot easier and less noisey. Nail those Spanish Mackeral and Dhufish with just a 100cm gun!

Years of research and development has been invested into the latest version of the MannySub Roller Power Head conversion kit. Simplicity and functionality have been the key focus of this project.

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

The bearings are light-weight and low-friction for maximum power transfer. Made from acetal, with encapsulated glass balls to stop sand and salt-water damage, these bearings are virtually maintenance free. They will ensure many years of trouble-free use.

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 manoeuvrability.

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 to spear-weight ratio yield significantly more power. Tests show a speargun with a Roller Power Head and a single 16 mm rubber will outperform a traditional speargun of the same size, with a double 16 mm rubber.

Any Euro/South African speargun with a cylindrical removable muzzle can be converted into a roller speargun with this system.

The Roller Power Head is available in black and comes with 14, 16 or 18 mm rubbers, one adapter, three different types of dyneema lines for the installation, stainless fittings and easy- to-follow rigging instructions.

Two wraps of shooting line is recommended when using 16 & 18 mm rubbers.

For optimum results this kit is best suited for spearguns ranging in size from 80 to 110 cm.
