This is my Assailment Gun (inspired by G1 Onslaught's rifle) that has a handle designed to fit those toys in the Alternators / Binaltech line. Assuming the Alts/Binaltechs have standard style hands this should fit them all. I only tested the handle design with the only Alternator that I have. If there is a weapon that I've already created that doesn't have the Alt handle available please send me a message and I'll try and create it for you.
