You wouldn't believe me if I told you what this part
is made from......wait for it......The smaller
head of an elephander.  it's turned upside down
and cut and altered so you probably don't even recognize
it.  Again I used the stabalizer cap and blox joint
design for the missiles though less obvious here since
the caps are imbedded inside the outer shell of the part.

There's also four smaller missiles from one of the
flexible booster units.  (I bought two, one I assembled
with guns and one assembled with missiles so I had
a leftover set of each)

The rear weapons are actually made from a bionicle set.
I bought one on sale to use for spare parts.

Various other bits of spare plastic scraps were used to fill in the gaps.

The mount is from a 120mm cannonry unit and turned so the
smaller hole is facing downward.  Finally I painted
it in a dull blue and gunmetal gray.

That's about it really.  Although I displayed it on the 
stealth viper I've since found it looks better on a 
molga.
