Double Roller Speargun Muzzle Kit - Crystal

Double Roller Power Head Muzzle Kit - Glass

The Double Roller Power Head - Glass conversion kit, made in Australia, is designed for those looking for a precise and functional double Roller Speargun Muzzle for freediving and spearfishing spearguns.

Design and Construction

The Muzzle features an innovative system with inline pulleys, characterized by different diameters: the front pulley is larger than the rear one. This solution prevents the Bands from overlapping and allows for compact wraparound along the speargun barrel, reducing bulk and hydrodynamic drag. The result is smoother, more controlled tracking during the shot phase.

Technical Components

• Robust main body, molded construction
• 4 pulleys with glass bearings for optimal smoothness
• Ultra-light carbon fiber side plates to reduce overall weight
• Integrated line guide, suitable for lines up to 3.2 mm thick
• Three types of Dyneema line included in the kit
• Barrel adapter available for diameters from 24.5 to 26.5 mm
• Bands available in 14 and 16 mm diameters
• Rocker linkage and detailed instructions for simple, correct assembly

Functionality

The integrated anchor point allows attachment of the Muzzle bungee. The dual line guide allows the shaft to be secured to the Muzzle, with the shooting line positionable on either the right or left side, offering greater flexibility in setups.

Configurations and Compatibility

• 2 pairs of 14 mm Bands to drive 8.0 mm shafts at high speed
• 2 pairs of 16 mm Bands for 8.5 mm shafts on 100 to 140 cm spearguns, delivering high speed and power
• Supports the use of lightweight 7.5 mm shafts with reduced pretensioning and 14 mm Bands

These options allow the kit to be adapted to the specific needs of the freediver or spearfisher, optimizing speargun thrust and accuracy.

Technical Advantages

• Minimized bulk thanks to the compact design of the inline pulleys
• Extremely low friction between the Bands, increasing propulsion efficiency
• Lightweight construction ensured by carbon fiber and the fiberglass body
• High mechanical strength and component durability
• Easy assembly and maintenance ensured by the illustrated instructions
