Reef Roller Muzzle

The company that created the Open Muzzle Revolution over a decade ago now releases a perfectly simple Roller Muzzle for reefs and in-shore environments. The Reef Roller Muzzle’s simple design keeps the shooting line away from the shaft and bands. Its low profile shape reduces drag and further adds to the stealth and power of the speargun. Made from Stainless Steel and Glass Nylon construction, the Reef Roller is the absolute perfect Single Roller (one band) set-up for all your spearfishing demands.

Roller Shaft

HammerHead’s proprietary Roller Shaft has the shark-fin welded to the flat of the shaft, eliminating shooting line tangles and maximizing band stretch. Made with a Loading Tab which also functions as an attachment for your shooting line, the HH Roller Shaft aids in loading the logarithmic band stretch of a Roller. Manufactured in the USA by HammerHead Spearguns.
