1) Shorten some new, blue 5/8" bands by 1-1/2". HanaPa'a carries it.
2) Get a good, no bullshit tip, ala a tricut, detachable and keep it sharp... I often find myself sharpening a tip after a dive where I haven't fired at anything, but upon reflection, recall using the gun as a prop to push off the bottom with.
3) Once a year, like when it's raining, pull the guts and take a little file and smooooth out the nicks on the sear.
4) You can find a titanium tube and have it turned down to fit the JBL muzzles and handle assemblies, but it can get a tad pricey unless you touch the machinist up with a couple filets. Wrap the barrel in black electrical tape to keep 'em from seeing you before you see them.
5) The older, as in OLD JBL muzzles seemed to be a bit larger and allowed a 4th 9/16" band, but I personally get frustrated and worried about that much rubber bunching up. Whatever the case, metal wishbones are de riguer, as in gently ease the notches on the shaft. And if you can source out the heavier wishbones, let me know- I'm out.
5) Replace the butt pad with a pad from Riffe or Wong that will spread the recoil if you launch with the thing too close to your body. And here arises a style thing- keep your gun arm pretty well locked. I've seen divers with bazookas I've made for them not be able to get the shaft to do anything as their body soaks up the recoil of the gun, by having their arm swing with the jolt, rather than being a foundation for the gun.
Pretty basic stuff when you think about it, but other than just adding the bands, there's not a whole heckuva lot you need to do but practice to dive better.
