I saw the Bruticus upgrade kit that adds barrel extensions to Onslaught's rather dinky cannons, then I saw that I had 2 plastic rolls left over from a couple rolls of dog poop bags. Decided to slip them over Hot Spot's guns because I had him handy, and tada! Instant weapon upgrade! Now Defensor has some proper guns: I'll need to sand and topcoat these so they'll fit Defensor better, but they're otherwise perfect for him as is. The ones for Onslaught will need paint, but should make him look much better in vehicle and torso mode. I'll post some pics of Onslaught when his are done, but first we'll need to use up a couple more rolls of the bags so I can have some more tubes.
