If you are a beginner spearo, starting off with rollerguns may not be a good idea as there are a lot of moving parts you need to handle, and with lots of moving parts, there are also a number of things that could go wrong. So if you’re just starting out, master a railgun before moving onto a rollergun. Regardless - it’s important to understand what rollerguns are and how they work.
Regular spearguns usually have a hole in the muzzle. When the rubber is stretched, it just goes up to a certain band stretch and when released, it basically loses its momentum and the shaft will just go in its initial inertia that was created by the band. With a roller gun, on the other hand, instead of the rubber starting at the front of the gun and loading to the notches at the back, the rubber comes from the underside side of the gun, goes around the roller at the front of the gun, and then is pulled down, loading onto the notches at the base of the gun.
So when a rollergun is loaded, you’ll have nearly half again as much rubber on the spear and there will be far more tension and kinetic potential. So the rubber pulls all the way to the tip of the muzzle. On a railgun, the rubber will pull two-thirds and stop there.
Whilst it may sound cool to have such great power when using a rollergun, you have to understand that there’s a chance you might lose accuracy because of the fact that it's so high powered. The spear's going out a lot faster and that causes accuracy problems. That is also why there has been plenty of people that have switched to roller guns and then later came back to railguns. So it comes down to personal preference.
