cine_m16 for M4/M16

[pixysolowing]

I was always bothered by the 20 round mag so I tried to replace the "M16" model with the "cine_M16" model and it resulted in this, I was wondering if anyone can achieve this? I assume the model isnt rigged to be playable so if anyone can do this or give me instructions/point me in the right direction it'd be much appreciated

I tried it, no idea why the gun is rotated 90 degrees
