This nifty little item Fakebuster made for me lets me mount the G1 Megatron arm cannon on the Takara Tomy Masterpiece figure. Here's a shot that shows both scopes in the same shot. Here's the project listed: https://www.shapeways.com/model/1768951/megatron-gun-adaptor .html?li=aeTabs&key=c66ae75a45c2d7e8c2d5f299c51fa23c Simple design, but I really think the G1 scope looks far better than the Masterpiece one, which is entirely too big.
