I'm pretty sure that problem could be solved if you remove the camera movement that occurs when pushing. Almost no addon has a camera movement during the push animation, and some of the ones that do, have the same problem with the gun sight being misaligned, when pushing and zooming, right after firing.
Could a weapon inspection animation be added in an update? Currently there are several Mods with inspection animations for weapons that don't normally have an " extend hand" animation. (Yes, for weapons like the knife, magnum, Counter Strike weapons, etc). So it is possible nowadays.
Your animations are amazing.(My favourite is the 357 of the ProjectHL2 mod)
