Stuff you'll need:
Small sanding drum or similar high-speed cutter
-Hot glue gun
-1/8" Polycarbonate sheet
The best place to start is probably the turret because it is nice and easy.
In order for the mod to work, you also have to do the "roulette mod."
After the "roulette mod," you have to disassemble it and then cut off the original barrels:
After that, use your bit of choice to widen the holes in the back of the turret. The hole should be wide enough to get a dart through but not wide enough for the petg to go through. You should have a small lip:
After that, all you have to do is cut and insert the petg:
I had the best luck with 2.5" barrels.
Now put your turret back together and sit it aside.
Onto the shell!
All you have to do to the shell is turn the oval-shaped opening for the plunger tube into a rectangle. The rectangle should be about 1" wide (2.5cm):
Now for the plunger tube.
I personally did the "straw mod" on mine, but it isn't necessary. You also need to get a good seal in the tube, so use whatever method you prefer (new o-ring, e-tape, etc.)
You also need to shorten the little oval that sticks out of the front on the plunger tube. After cutting it down, it should be about half the length that it was originally. Be careful with this part because if you leave the oval too long, the turret won't be able to rotate.
Now, for the rear-loading to work, you need to make the turret seal against a larger area than that little oval. To do this, cut a rectangle of polycarbonate that fills the rectangle that's cut into the shell of the gun. You have to make sure that it's large enough to cover the entire hole in the back of the turret. Once you cut that rectangle, attach it to your plunger and drill a hole in where the opening is:
This will probably be the trickiest part of the mod. You have to get that rectangle large enough to seal but not so large that it doesn't fit with the turret in.
After doing all of that, I would recommend that you do CaptainSlug's mod of relocating the trigger spring and gluing the clutch together. If you do that mod, your turret should rotate pretty nicely.
Put it all back together and you're done!
I don't have officially measured ranges, but I am getting about the same ranges as I was with the mav on Miget, so this mod definitely doesn't hurt ranges, and in most cases, it will probably help your ranges because it now has a good seal.
I realize that the mav isn't the greatest, but there is already one stuck to my LS, so I am going to try to make it decent, at least.
Questions? Comments? Insertion into the mod directory?
Thanks for reading!
