Exactly the same as the M.A.C.O. Mk XII weapon, and just as lame. (Everything is simply a copy of M.A.C.O. for KHG Adapted, and M.A.C.O. Adapted is a copy of KHG.)

I just got it for the outfit. Using the regular Mk XII set still.

As for what the weapon looks like, I don't plan on taking a picture of it, but it's basically a longer looking version of the KHG pulsewave and still has the bayonet. Weapon fires in green but has Phaser damage.
