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

This invert roller head has been cleverly designed with many fantastic and unique features:

• 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.)
• Stainless steel line guide, line wrap fingers and pull line stopper.
• Invert pulley wheels have a large surface area rotating bush for minimal maintenance and high performance. 
• The central body is CNC machined of super strong delrin material.
• Very compact design.
• Comes with 2 stopper washers and 2 fast screw adapters.

This unique design offers more than an invert head alone. Wheels and axle can be removed and using the provided fast screws fixed to the pull line holes, you can now turn the head into a single high mount rubber head.
