Need help: Broke peg off of Megtron's stock
 

So I was a little careless with my new Revoltech Starscream's Megatron's stock. I thought the thing looked a little too small to be a good post and lo and behold it snapped off in the thing. Now it stuck and i don't think heating it up taking it out and putting back in is a good idea. the only reason the stock need to come off is because the damn hand isn't wide enough for me to just place the gun in it. I have to remove the stock and slide it in. Can some one pleae help me?

I would try some zap-a-gap superglue. It's the best I've ever used.

But I need to be able to remove the stock afterword.
