That picture isn't even set up, I actually have all my shit laying around in my basement like that. :P Been outa practice for a while so I have been running mag drills and transitions.
Anyways Yes I got a hardcase with mine, but I got it used. I have the long barrel extension as well as seperate inner barrel and hop up units to allow for "quick" barrel changes. As quick as a SCAR can be, seeing as it is probably the hardest/slowest AEG to actually do an inner barrel change out on.
