Single Roller Speargun Muzzle Kit - Crystal

Single Roller Power Head - Glass Muzzle Kit for Spearguns

The Single Roller Power Head - Glass Roller Speargun conversion kit, made in Australia, is designed to improve the power and accuracy of spearguns for spearfishing and freediving. This system eliminates traditional recoil by optimizing the use of barrel length for more effective and controlled power transfer.

Technical Features

• One-piece main body made from robust molded material for high mechanical strength
• Two pulleys with glass bearings with low friction, made from acetal with encapsulated glass balls to withstand sand and salt water, reducing maintenance and ensuring long-term durability
• Ultra-light side plates in carbon fiber to ensure lightness without compromising strength
• Integrated line guide allowing the attachment of shock absorbers or lines up to 2.5 mm thick
• Complete with three types of dyneema line, barrel adapter, and rocker link
• Available with 14, 16, and 18 mm bands and adapters from 24.5 to 26.5 mm, to fit different speargun sizes

Benefits for spearfishing and freediving

The roller system allows 100% of the barrel length to be used to drive the shaft, increasing generated power thanks to the pretensioned bands and an optimized ratio between band stretch and shaft weight. This configuration improves the accuracy, penetration, range, and handling of the speargun. The use of lightweight yet durable materials also contributes to smooth movement and better trim in the water.

Compatibility and Use

• Compatible with most Euro-style or South African-style spearguns equipped with a removable cylindrical muzzle
• Recommended for spearguns between 70 and 110 cm in length
• Also high-performing on 120 to 130 cm spearguns when equipped with 18 mm bands

Installation and Maintenance

The kit includes detailed, easy-to-follow assembly instructions, allowing for a quick and efficient conversion. The low-maintenance bearings reduce wear and ensure reliable use even in saltwater environments.
