Transformers Prime Beast Hunters optimus prime voyager gun custom
I got bored, and I don't care for the missle launcher even though the missle goes pretty far, so I decided to take DOTM voyager Shockwave's gun tube thing, attached it to FOC Starscreams gun, and there you have it
It's not hard at all, you don't have to tab anything in, and I had lots of fun.
You don't need any tools. The only hard part is that the wire thing is hard to put into Prime's back the first time. You'll have to take it off to Transform, and you can't really store it in vehicle mode. It's even cooler in my opinion to the show's gun
