Next thing you have to do is get rid of that stupid stock biller slide ring assembly. I just changed mine out and got a more streamline spear and accuracy and speed are much better. They sell low profile slide rings which are a lot better. I also got rid of the metal spacer that fits into the muzzle, took the muzzle off the gun and placed it in boiling water and then used some locking pliers to bend the muzzle tighter. End result is a big improvement over the stock biller setup. But just the slide ring will help a lot. Newport Dive Center sells them online.
