If you weren't so damn far away I would fill it and ship it for the movie. I can get the measurements if someone you know is good with wood or metal.....
i was looking at something similar the other day. i wouldnt mind haveing that around. and you can buy a row of glock holders that go straight down. a but pricy but are nice none the less.
Very nice... acquisition there Ithica your collection is coming along fantastically. Good work throwing the AR in for the vid, it really added to the jaw dropping effect.
Nifty! You should grab some shotguns to put in, real easy to make from existing airsoft models. Only $20 plus a quick maglight attachment and you're set. Now what to do with all my covenant weapons hehe....
I think you could do it with wood pretty nicely. Perhaps plywood would work. It's usually cheap (or in my case there is always some lying around from one thing or another). You'd have sand it a lot,but you could probably use varnish or something to get the shiny metallic look.
