This stuff look amazing, the one thing i would point out is that, even though it's really well crafted, the reload animation seems a bit too relaxed, I think it would look a bit too casual when used during a firefight. Keep up the great work!
Quite interesting animations you've got there Brightside, although I'm not sure about the reload that just seems to not really fit the rest of the animations too well. Origin looks a bit too close to the left as well although compared to the shotgun it does seem to be the default for these redone models. As for the sounds…
