as soon as you order them they get shipped. wherever it says "in stock" on the jibij website means that it's physically in the store. if it says "preorder" then, well, it's a preorder and you won't get it until the shop gets it.
Some of the colors are reversed on next years k2's remeber.. so some publics have a red base... some have a white... and same with the silencers... some have a white base... some have black. Its a way of making the most out of the base material. But pretty cool too... cuz not all of them are the same.
