Sigal Nemesis HT Invert Roller Head is a quality Italian made tube speargun head for converting or building your own inverted roller speargun. 

This muzzle is one of the extraordinary works of art of the Sigalsub Nemesis HT. Its design allows for an extremely low weight and a compact shape.

• Amidextrous front shaft line wrap fingers
