Hey guys, I have had MP prime ever since he first came out. I think he is the #1 transformers toy of all time. He came with some cool accessories especially a mini megaton gun! Only problem is... the stock breaks very very easily at the hinge. A replacement is very costly on ebay and thats about the only thing you can do. I decided to try and repair mine. Not with glue because that would just not work as the plastic is just too soft. Even if it did work for a bit it would ruin the pistol part as it is supposed to be removable. What I decided to do is cut off the hinge part and then cut/slowly file a grove area in the stock that would fit right on to the pistol. When finished I was happy with the results. It is not perfect but, good enough for me. If I were to do it again I would use a different mini file. With that I think it would be really nice. It holds ok for display and comes right off when needed. On to the results.
