This includes Reverse loading, AR removal, and Paintball firing.
Step 1: Part I: Butterflication
Butterfly the strongarm. Keep the screws in a safe place. When you take off the cocking handle, a spring will be screwed to one half. Remove the screw and spring, but PUT THE SCREW BACK IN. It is notoriously easy to lose.
Step 2: Part II: Reverse Loading
Remove the cylinder. Drill through each of the barrels with the 9.5mm drill bit. Drill through the back. When you take the cylinder out, some of the guns' guts might come spilling out. Also, the front grey bit of the cylinder might fall out. That's okay. Both easy fixes. This mod is really only useful for firing stubs (half darts).
Step 3: Part III: AR Removal
Remove these three parts. The trigger needs a screw undone. The T-shaped bit is in the top right corner, and the tiny orange thing is in the middle of the tact rail.
Step 4: Part III
Remove the gut package from the gun. Pull out the firing tube, or the big orange cylinder. Make sure you keep its little spring safe. Pull the finny shaped end of the tube, and a big thing with a big spring (ahhh poetry) should come out. Now drill through the middle of the foam ring until weird things stop coming out. Try not to damage the seal too much. Put the gun back together now.
Step 5: Part IV: Paintball Firing
As for the paintballs, just plonk one in, push it in, cock, aim, and fire!
See my jolt article for what kinds of paintballs to use.
