Arma 3 Belt Fed Model Animation

[warlord554 2065]

I'm working on custom weapons pack. I cannot get the belt fed machine gun to animate. I used A2 model cfg bases. What has changed between the two games? I'm sure the bullets or axis are named differently but I don't have the tools to extract m200 lmg model cfg. If someone knows the classes or can post an A3 model cfg it would be a big help.
