Porting animations from CoD5/CoD4 to CoD2

Aha! Finally got the weapon to move with the hands!

Turns out it was a very simple fix that did it. I just had to remove the name of the imported file from all the joints.

Here's what I mean: after I import the Barrett M82 into the scene, the joints will be named "viewmodel_law_barrett:joint_name"
where "viewmodel_law_barrett" is the name of the imported model's file, and "joint_name" is the name of whatever the joint is. So I just had to remove the "viewmodel_law_barrett" and I finally got it working!
