FX Impact dimensions question

Very basic questions:
1. Can the standard 600mm version fit Inside the box with the moderator still attached to the gun? I know in the sniper, you'd have to remove the moderator - wasn't sure if that's also the case with the 600mm.
2. A 600mm version with the bigger sniper bottle - will the barrel still extend beyond the bigger bottle? Or will one need a moderator to extend the length beyond the bottle (similar to what they do on compacts with bigger bottles)?

Thank you.
