Looking at the typical Halo weapons (DMR/BR & Assault Rifle), it seems like it wouldn't be too difficult to make a cast of a completed product for easy reproduction. Obviously, smaller parts like triggers and perhaps the barrel itself would need to be made/added separately, but overall, the form of the gun looks easy enough to be reproduced through casting. Thing is, I can't seem to find anyone who is does this. Does anyone do this? If so, can someone point me in the right direction please?
