The Mannysub Double Roller Muzzle is the perfect modification for your speargun to add extra power when landing those shots! The new inline design by Mannysub is slim profile, lightweight, functional, well-constructed but most importantly, ACCURATE!

The innovative inline design allows the rubbers to hug the barrel tightly in a circular way for a low-profile fit. This reduces drag and bulk significantly compared to other roller designs!

The bearings are lightweight and have low friction allowing for maximum power transfer. They're made from acetal, with encapsulated glass balls to stop sand and salt-water damage, these bearings a pretty much maintenance-free.
