The Mannysub Roller Muzzle is the perfect modification for your speargun adding smoothness and reliability so you can catch that Kingfish with precision and power! The new inline design by Mannysub is slim profile, lightweight, functional, well-constructed but most importantly, ACCURATE!

With the elimination of recoil and generating more than double the power for a given barrel length, the Mannysub Roller Muzzle offers higher accuracy, penetration, range and manoeuvrability.

Bearings are lightweight and have low friction for maximum power transfer. The bearings are made from encapsulated glass balls to stop sand and saltwater damage.

Common Setups with Roller Muzzle:

A speargun equipped with the Mannysub Roller Muzzle uses 100% of the barrel length to propel the spear. Pre-tensioned rubbers and a greater rubber-stretch to spear-weight ratio yield significantly more power. Tests show a speargun with a Roller Power Muzzle and a single 16 mm rubber will outperform a traditional speargun of the same size, with a double 16 mm rubber.
