For this mod your gonna need:
2 5" pieces of 1/2" PVC
2 1/2" PVC couplers
2 5" pieces of whatever size brass you use (I used 19/32 brass because my darts are kind of fat)
If your brass isn't very restrictive then get 2 2"-3" pieces of 1 size down brass. (2 2" pieces of 9/16 for me)
Hot glue (With some extra hot glue sticks)
Something to cut brass and PVC (I used a saw and miter box)
Dremel (You don't need the dremel, but it makes things easier.)
Ok, first, unscrew your gun. It's nice and basic. No hidden screws. Total of 5 screws.
Then take the barrel + plunger case piece. Cut the barrels off, and dremel it down until you have wider holes for air to pass through.
Now put that aside, it's finished for now. It's time to make your barrels. So heat up your hot glue gun, and wrap both of your 5" pieces of brass in E-tape so they will fit in the PVC. Now, if that brass isn't very restrictive, then nest your 2 smaller pieces of brass inside those. I had a little under a 1/2" of the nested brass sticking out theend of the barrel so the dart was closer to the air supply, but make sure it's not sticking out too far, or your barrel won't fit in the coupler.
Now, get your PVC and couplers, and nest your brass barrels inside the PVC. Put a tiny bit of hot glue to secure the brass in there. I put E-tape around the PVC barrels so it looked better.
Now you need that barrel + plunger case piece you cut earlier. Hot glue a coupler on each barrel stub. I added E-tape to hide the ugly hot glue. You could use Epoxy here, which would hold much better, so would Plumbers Goop, but I felt it didn't really need it. Then, screw your gun back together.
And now your done!
I don't have any official ranges yet, but both barrels can go across my hallway and hit the door about 20' away without any drop. I'll get ranges up probably on Friday.
I will probably make some shotgun barrels later, I don't have the supplies right now.
I don't know if I left anything out, but if I did tell me and I'll change it.
