Mod: MEGA Centurion

Apologies for taking so long with this.

BE FOREWARNED. This is the craziest nerf gun I have ever tried to dissemble and reassemble, let alone modify. I'll give you a clue: if you don't like multitasking, this mod is not for you. The good side of it is that I was able to get a consistent 15-20 foot bonus in range, plus much better accuracy at range.
If you're willing to sacrifice your sanity for these advantages, proceed.

Difficulty: VERY difficult.
What you'll need: A strong person, a long, thin, hopefully magnetized phillipshead screwdriver, electrical tape, a place to keep screws organized.
Suggested: Needle-nose pliers and an insane amount of patience.


1. Remove stuff
You'll want to first of all remove the clip to keep things simpler later on.

The front barrel

Then get your strong person to pull the front barrel piece off. Don't worry, this won't damage the gun or the barrel, and you can put it back on when you're done if you want. Just pull it straight off the front, and you'll be fine. Final, crucial step before you take it apart: make sure it is de-primed. Otherwise it will explode. WILL.


2. Unscrew
There are 24 screws total in four sizes. Get organized, or stop here.
The screws come in short, medium, long, and LONG. The five short ones go on the tac rail and the farthest left spot. The two LONG ones go at the top of the stock and in front of the jam door. The three long ones go here:

The medium ones go everywhere else.

3. Clamshell

Pull the halves apart. The little orange piece in the tac rail probably won't go flying (for once), but it's still good to be careful.

The internals

4. Lock removal

The two locks you should remove are located behind the trigger system shown below.

The trigger system

This is what one of the locks looks like. The other one looks similar.

Trigger and locks removed

First, take out the 2 screws holding the trigger system in. Take that out, then pull out the two locks behind it. It should look like the picture to the right. Then put the trigger system back in. Make sure to slide the end under the catch system. Screw it back in.

5. AR removal/seal upgrade

First you need to take off the white gear and orange "gear shield". Then take out the whole big plunger system. In order to fully remove it, you need to unscrew the return spring, housed above the main plunger tube. After that, you need to unscrew three small screws that hold the narrow front section to the bulky rear half. Simply pull out the pieces shown below (along with the spring that comes with them), and screw the front back on.

Then, take your electric tape and wrap it around the plunger tube to seal off the vents on the side.

One vent sealed, one to go.

Both vents sealed.

6. Extra improvements

If you want to make it easier to clear jams, you can pull out the jam door without affecting performance in the slightest. This is helpful for seeing when you're out of ammo so you don't dry-fire it. Another thing to do to make jams easier to clear would be to sand down the edges of the top of the clip so the darts can actually squish through the gap if you need them to. Additionally, if those green "priming indicators" bug you as much as they do me, you can safely remove the green parts ONLY. ----->

7. Homework

Take apart the clip well and remove the lock that prevents use when the barrel extension is not attached. You're on your own for this one, since I forgot to note down how to do it (and there is NO chance I'm doing it again). But I'm sure you can figure it out! Just remember to remove as little as possible, and keep track of where everything goes. Good luck!

8. Reassemble
Put everything back where you found it. You can use the picture above to try to tell where everything goes, and remember to screw everything in right. If you don't, you'll have to take it all apart again when the internals go kablooie the first time you try to use it. I'm sure you don't want that.
After everything's arranged, make sure that the priming handles are aligned, and put the top half back on. Easier said than done, so be patient.
When that's all through, you can screw it together. If you pulled out the lock in the clip well, you can stop here, leaving the barrel extension off to get slightly better range. Or, if you didn't, or you just like the tacticool "sniper" look of the complete Centurion, you can snap the barrel extension back on.

AND YOU'RE DONE!!!

Give yourself a pat on the back. Better yet, get someone else to give you a pat on the back. After all, you just disassembled, modified, and reassembled the Nerf MEGA Centurion. You deserve it.
