Wow, thanks for all the feedback. I'm going to have to ask around to see if I can find a plastic supply store around me. Does the IPS end up costing less? It's not too cheap for a tube of Plastic Weld, after you buy 4 or 5 of them, and I'm maybe half way done on the gluing portion of my suit, not including the rifle!
I understand what your saying with the trigger, and I can do that, it shouldn't be too hard. I can see why you would do that too, the trigger area has no support, so it could just crumple under pressure, not to mention it could just break if your not too careful with it.
As for the lighting, I may attempt this. I'll have to draw up a template for how the lighting looks on the side, and top. I'm thinking that the easiest way to make it work is to use the method I've seen for cheap Fett chest lights, using some clear plastic sheets you can print onto, and printing out the template, then putting one of those bicycle lights behind it, and so on. It's the TK-409 method he has up on his site...

It's in the center column, near the bottom.
I'm thinking I can do this without too much crazy work. The only complicated part is going to get it so I can still change out batteries, but if I make the gun separable, this shouldn't be a problem.
When I get out of class I'll take a quick video of the blinking on the gun. The lights on the sights are the only part that blinks, from what I can tell.
So, what your saying is that if I don't glue the PVC to the butt end of the gun when I put the "Great Stuff" in it, the "Great Stuff" won't hold the PVC in place? I think I got what your saying... This could make the electronics a lot easier to work with.
Is there a way I can order IPS online if I can't find a local distributor?
Thanks again for all the help!
