I started with four Nerf N-Strike Loneshot CS-6 guns. All the guns were striped down I removed some parts like the Tripods. Parts of the tripods were re used for the support for the Fuel container alone with a big chunk of polycarb.

The fuel containers are stainless water bottles, little bit of paint and a role down my drive way to weather them a little.

The Scope was dressed up with a few PVC pluming pipe parts.

For Some of the plastic parts I started with a adhesions promoter. All the parts were then rattle can'd silver and then two coats of clear were sprayed. All the parts I wanted gun metal were sprayed over the silver. Then the gun metal was light sanded to expose the silver underneath.

The coolest thing was the EL wire (Electroluminescent) that was run dow the inside of the gun by the barrel.
