Making a mold of a trigger pocket

[okmedic]

I realize this is an odd question, but if one were going to make a mold of an AR15 trigger pocket, how would one go about doing it? I'm looking to make an entire mold of the inside of the entire trigger pocket and it doesn't really make a difference what material it is, it just needs to be strong.

Thanks fellas.

look at the material people use for chambrr casting. melts at 3 or 400 pulls out easy. cerosafe or something like that. cant remember the name.
