Hello, I'm one of those kids of the 80s who maintains an interest in G1 toys but doesn't know much that has happened since. I could use a little expert info. Is this just a basic Megatron reissue? Is it complete? This gun is VERY similar to G1 Ransack's concussion blaster gun. Did all Ransacks come with a black gun, or is this a variation of his weapon? If it's not a G1 weapon, can anyone tell me about it? I don't think these are G1 accessories. Does anyone know which toy they belong to? Thanks!
