Step 2: Handle

 Follow the pictures.

Step 3:

Follow the pictures, and build two of the barrels.

Step 4: Assembly

Follow the pictures, then the video.

Step 5: Loading and Firing

Follow the first picture.
Load before you add the exterior.
Hold the handle and shake the gun up and down. To fire more accurately, shake gently. To fire rapidly, shake it move vigorously.
Semi automatically:
1) Hold the bottom of the gun with your other hand and pull the trigger .The trigger is not supposed to move. Pulling it causes the handle to move.
2) Reset the handle by moving the bottom of the gun backward.

Video Here:

It reloads in a similar manner to plasma pistol, but you alternate between barrels to reduce the risk of firing when reloading.

    Sorry for the double comment.



    this is awsome i am customizing it now that i have built it

    Cutting the yellow connector is optional. It's not necessary, but it would jam less often.

    Unless you can find a way to load the gun whit the outer shell on, then yes, you will have to load it before attaching the shell. It works perfectly fine without the shell, but won't look like the Halo plasma rifle

    i love the halo series, and i am happy to see that someone has made such an awsome replica ; ] does any one know how to make a good needler
