Silicone sealant (or Goop if you don't mind it being permanent)
Tiny amount of epoxy putty or glue of choice
Step 1: Open the gun, watch out for a screw under the pump and a piece of tape along the top.
Step 2: Take a look inside, pull out the turret and plunger tube, try to keep everything else in place.
Step 3: Take the plunger tube. At the front is a white piece of plastic that forms a seal with the turret. Take your sealant and place it between the white piece and the orange part of the plunger. The sealant should hold the white piece a mm or 2 forwards so it makes a good seal when the turret is in place. Here's what it should look like when placed back in the gun.
Step 4: Take the plunger head, and wrap once with E-tape and fill in all dead space with hot glue. I apparently forgot to take a picture of this, but it is exactly the same thing that Darken did in his mod. My plunger had no lube in the tube when I opened it up so if you do this make sure to lube it after.
Now we move on to the turret.
Step 5: There are 4 screw holes on the back of the turret, unscrew them all, and the turret should open right up.
See that piece I crossed out? It is 100% NOT needed, and can be thrown away immediately.
Step 6: Cut the front of the turret like shown, to fit whatever barrel material you will be using.
This picture also shows the back of the turret. Place your sealant along the flat part inside those rings at the bottom. Now reattach the two turret pieces, and slide your barrels in through the front. Those 3 pieces of plastic sticking in were the exact fit to stabilize my cpvc on the bottom. You may have to trim them if your barrel material is larger in diameter. After this step my barrels were air-tight.
Step 7: The barrels are in place, now we just have to keep them there. I used a small amount of epoxy putty like so.
I could have used more, but this seems fine so far, and I didn't want it so heavy that it messed up with the rotation. There doesn't appear to be any type of slip-mech like in a Maverick or Firefly, so you will always want to rotate the turret by pumping.
Step 8: Put everything back together. I found it necessary to prime the gun a small amount to get the plunger to sit flush with the shell and catch mechanism, but that might not be true for everyone.
Step 9: Enjoy!
Extra Thoughts and Ranges:
I thought about making this rear-loading. I believe it wouldn't be too hard, but there are 2 layers of plastic to go through. After that the holes on the turret and the plunger/turret seal would need widening. I'm kinda lazy, so I'll let somebody else attempt this.
My barrels are probably around 9in long. I didn't really measure, just looked at the mod pictures of the Lanard Hand Cannon that are around and guesstimated the length they used.
The rotation seems a slight bit off, but my ranges were better when I left it alone then when I adjusted it after rotation.
Ranges varied from 50 to approximately 80 feet. I'm going to wait for everything to cure and find a slightly longer ramrod before I test them again. I did not add a spring yet because the one already inside is awesome, and I want to see how other spring additions go before I break my gun.
I hope you guys found this write up informative and easy to follow. I would recommend this blaster to anyone, and I'm sure there is plenty of room for improvement in the future.
Edit: I shortened the Barrels by a couple of inches, and the ranges are much more consistent now. I shot 12 darts off, 2 went into the high 70's, the other ten were between 50 and 60 feet.
