anyone experienced with cutting metal?
 

I'm trying to do a project that involves reducing the size of a magazine. It doesn't need to function, just externally it has to look presentable.

the first pic is the cut

so basically to make the 40 rd mp7 mag into a 30 rd mag.\

maybe there is someone in the GTA that can take on the job with a donor mag. fees on me of course.

I imagine a chop saw with a metal diamond blade would do it, then just jb weld the bottom on.
