pics 1-4 NARP (not a the first one)
5-7 TR-12 (A mod a Whaleman's turret)
The NARP suck because of its red rod ram( giving it suckish range compared to the nar) but it was fun to make.
TR-12 is all most as good as the TR-18.
The only thing it lacks is the six barrles that the TR-18 has.(it makes that up becosue it is not much lighter
