If you're talking about what I think you're talking about, there are only two hose pipes in those. Also, the megaphone blaster is awesome enough than an entire army wielding them would be totally fine. I approve.
I would suggest changing the colors on some of these though. On the dark grey rifle and shotgun find some dark grey clips instead of the light. It doesn't flow well. A lot of these could look a lot better with just some color change.
I like the fourth rifle on the right (top pic) Great modification of the LA Blaster, I wish I had thought of doing that with mine. The suppressed Space-wars pistol is so simple, but it still looks great, Kinda remids me of the Type 67.
