This is a minigun with 5mm pegs (left long so that you can trim to your liking ensuring your figure can hold it.). It features the modified Autobot "Wreckers" symbol on it.
I'd recommend a Strong & Fkexible material
If you want one with a different symbol or embellishment let me know, I can make one.
Edit - 12/10/12 - Made the exhaust pipes a little meatier so they won't be brittle.
