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

This new roller muzzle features a smooth surface to facilitate the sliding of the lines. It is also equipped with two self-lubricating POM rollers, a material with exceptional wear resistance, which rotate on a stainless-steel axle.

• It is made of Glass loaded Nylon, but the percentage is not too high to maintain the smoothness of the surface of the material and thus allow good sliding of the elastics and lines.
• The rollers are mounted with a five-tenths-of-a-millimetre clearance to ensure maximum smoothness.
• Two re-wrap midline to the side for shooting line side line wrap fingers
• Amidextrous front shaft line wrap fingers
• Pre-drilled for horizontal pin fit
• Delrin pin provided
• The spigot comes with a 26mm diameter double O-ring adapter for fitting most speargun brands in the market (Rob Allen, Aimrite, Pathos, Picasso, Salvimar, Cressi, Seac etc.)
• Comes with Sigal cup faced tensioning bolt to suit round tubes.
