ZZap gun bonus feature extravaganza

I know I promised killa kans last week, but I just have to show you my newest find. They are called Lag Shields. No, its not a new way to lower your ping in BF 2142. Lag shields are used to anchor bolts into concrete. But for our purposes, they are used as the bases for some nice looking zzap guns for a battle fortress.
I probably wouldn't use them on stand alone big guns, as they look too bulky, but their size works well on larger vehicles. Just look at how much better they look than the old zzap guns I started with. Slowly but surely, the battlefortress is taking shape.
