Mannysub Roller Power Head Kit 16mm

A lot of research and development has gone into the latest version of the roller power head kit. Simplicity and functionality have been the key focus of this project. Any Euro/South African speargun with a cylindrical removable muzzle can be converted into a roller speargun with this system. 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.
