610 Green Muzzle Kit - Pulleys with Bearings

Muzzle 610 with Bearing Pulleys - Sigalsub

The Sigalsub Muzzle 610 with bearing pulleys is the benchmark roller solution for anyone looking to convert or upgrade their tube speargun with a high-performance system. Part of the renowned Sigalsub Roller Speargun Line, this muzzle is designed to ensure maximum line travel, greater shot power, and long-lasting durability, even in the most demanding spearfishing conditions.

High-Smoothness Bearing Technology

The standout feature of this muzzle is its pulley system with double radial bearings made from a non-metallic technical material, with 316 stainless steel balls. The bearings are equipped with an outer cover that prevents sand, seaweed, and debris from entering between the balls, ensuring consistently perfect, friction-free rolling. The dynamic load rating of over 45 kg guarantees reliability and strength even with high-tension bands.

Construction and Materials

• Central body made from glass-fiber-reinforced plastic material for high mechanical strength
• Stainless steel stopper for maximum strength and resistance to marine corrosion
• Double integrated watertight O-ring seal for perfect barrel sealing
• Pulleys with double radial bearings and 316 stainless steel balls with dynamic load >45 kg
• Available in black and military green

Compatibility and Installation

The Muzzle 610 is designed for direct installation on any commercial female tubular-section barrel. It fits barrels with an internal diameter of 26 mm (compatible with Seac, Pathos, Salvi, Cressi, and others) and is also available with a 25.4 mm adapter for Seatec, Omer, and similar barrels. The fastening system is quick and simple using a self-tapping screw.

• Compatible with barrels with Ø 26 mm internal diameter (standard)
• Ø 25.4 mm adapter available separately
• Bilateral side line passage: can be used on either the right or left side
• Fastening with included self-tapping screw
• Compatible with bands up to 16 mm in diameter

Complete Kit Included

The muzzle comes complete with everything needed for installation and immediate setup on your speargun:

• Complete roller speargun muzzle with bearing pulleys
• Two burnished stainless steel hooks for band pre-tensioning
• Burnished line guide
• Mounting hardware
• Instruction sheet with step-by-step installation instructions

Advantages of the Roller Speargun System

The roller system allows you to use the full working length of the barrel for band propulsion, unlike a classic traditional speargun, which uses only part of it. The result is greater shot power for the same speargun length, or the option to use a shorter barrel while maintaining the same ballistic effectiveness. The Muzzle 610 is the ideal choice for anyone looking for a reliable Made in Italy component designed specifically for the needs of professional and recreational spearfishing.
