That only happens (same goes w other CSS weapons like Scout, AWP, and SG552) when you have a script mod installed that's never been updated to the last stand update, because both original and this are correct, so it's yours, not mine nor original's

For some reason this puts the model on the left side of the screen

nice! I'm pissed off with these large size weapon skin, glad you made it!

Dokun homerun!!!
