Compared to traditional band spearguns, these systems modify the attachment point and routing of the bands, distributing thrust forces differently and changing the power profile during loading and firing. The result is different ballistic behavior, with direct implications for range, trajectory, and shaft impact force.\u003c\/p\u003e\n\u003cp\u003eThis section includes all \u003cstrong\u003eRoller Speargun and inverter accessories\u003c\/strong\u003e for spearguns: complete muzzles, pulleys, blocks, loading aids, stoppers, anchor bases, frames, and conversion kits. The products available allow both the new setup of a speargun with a Roller Speargun or inverter system, and the replacement of worn components or customization of existing configurations.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eProduct Types\u003c\/h2\u003e\n\u003ch3\u003eRoller Speargun Muzzles\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eRoller Speargun muzzles\u003c\/strong\u003e are the main component of the system. Available in \u003cstrong\u003esingle\u003c\/strong\u003e and \u003cstrong\u003edouble\u003c\/strong\u003e versions, they mount on the front of the speargun and determine the number of active pulleys and, consequently, the force multiplier applied to the bands. Single muzzles are used on one- or two-band configurations, while double muzzles are used when you want to maximize the available power on spearguns with greater mass and length. Each muzzle is available in different versions and with different bearing types: crystal ball bearings or ceramic ball bearings.\u003c\/p\u003e\n\u003ch3\u003eInverter Muzzles and Inverter Kits\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003einverter\u003c\/strong\u003e system differs from a simple Roller Speargun in the geometry of the band routing. In this configuration, the bands contract in the opposite direction compared to a classic band speargun (hence the name inverter). The band anchor point is in fact under the speargun and in the reel area, rather than at the muzzle. The available inverter kits include the muzzle, guide pulleys, and the fastening components needed to complete the conversion. Kits are available for both cylindrical barrels and wooden stocks.\u003c\/p\u003e\n\u003ch3\u003ePulleys\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePulleys\u003c\/strong\u003e are the components that guide the routing of the bands (or the line connected to them) within the Roller Speargun or inverter system. Available in different types—ceramic, crystal, standard versions, and with ball bearings—they determine how smoothly the band runs during loading and firing. Ceramic pulleys stand out for the hardness of the material, which reduces friction wear over time, while crystal pulleys offer a consistent resistance profile at an affordable cost. Pulleys are offered individually or in pairs, with different diameters depending on compatibility with the type of speargun or desired system.\u003c\/p\u003e\n\u003ch3\u003eBlocks\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBlocks\u003c\/strong\u003e are redirecting devices used in inverter systems or vela systems, where they change the direction of band travel.

Many Roller Speargun conversion kits and muzzles are designed for cylindrical barrels of specific diameters—typically with internal diameters ranging from 24 to 26.5 millimeters—and are not interchangeable between different formats. Likewise, inverter kits for wooden stocks have different construction characteristics compared to those for cylindrical aluminum or carbon barrels.\u003c\/p\u003e\n\u003ch3\u003eSingle or Double Roller Speargun System\u003c\/h3\u003e\n\u003cp\u003eThe choice between a \u003cstrong\u003esingle Roller Speargun muzzle\u003c\/strong\u003e and a \u003cstrong\u003edouble Roller Speargun muzzle\u003c\/strong\u003e directly affects the force multiplier applied to the bands. A double Roller Speargun configuration uses two pairs of active pulleys instead of one, allowing twice as many bands to be used at the same length. The double Roller Speargun muzzle is generally used on spearguns over 100 cm in length, intended for hunting large pelagics or bottom species that require long shooting distances.\u003c\/p\u003e\n\u003ch3\u003eCeramic or Crystal Bearings\u003c\/h3\u003e\n\u003cp\u003eThe difference between pulleys and muzzles with \u003cstrong\u003eceramic bearings\u003c\/strong\u003e and \u003cstrong\u003ecrystal bearings\u003c\/strong\u003e concerns service life and resistance to the marine environment. Ceramic bearings are made of zirconium oxide or silicon nitride, materials that resist saltwater corrosion and maintain smoother rotation over the long term. Crystal bearings (borosilicate glass or similar) offer comparable performance in the early stages of use but tend to degrade more quickly in high-salinity environments. The choice of bearing type therefore affects the required maintenance frequency.\u003c\/p\u003e\n\u003ch3\u003eSupport Accessories\u003c\/h3\u003e\n\u003cp\u003eFor spearfishers who use high-powered Roller Speargun spearguns, the use of a \u003cstrong\u003eloading aid\u003c\/strong\u003e or load assist device is recommended because it reduces the muscular effort required during loading. The reel mount base compatible with Roller Speargun and inverter systems allows the reel to be integrated directly onto the speargun without interfering with the band routing.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eAvailable Brands\u003c\/h2\u003e\n\u003cp\u003eThis section includes products from the following specialized brands:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMannySub\u003c\/strong\u003e: this Australian brand offers single and double Roller Speargun muzzles of the highest quality level in terms of strength and functionality.
