Upper handguard with rails for CM.045A

Designed this as more of a challenge for myself to see if I can make a part fit something premade and maybe make it useful too. The rails on top are sized to STANAG so they should fit anything of the same type.
I haven't tried it out in a game yet so I cannot guarantee it will survive any kind of beating. I will post updates as I try stuff out with it.

Also, pardon the poor images, they were taken with a phone and the black PLA isn't the best to photograph.
