Wel these are all the stuff I've done for the accesories.
So the gun

I done two for my display one for robin other for batman and basically one was the face off punisher jigsaw gun painted and the other one is a punisher gun with a iron man 2 war machine bullets bit glued onto the bottom then painted

The stickey bomb gun now thats my pride and joy
I used a halo gun and put that totgether and bits and I even made the bit you see I made that move up and down.

The batarang was plastic and baout 7 different tries of getting the shape right and thats it.

And last is the mask
I got a mask used a drill and made it bigger and bigger in drill size till I got to my biggest drilbit wich fitted perfect as it goes over the bruce wayne head.

And thats it all
