I've seen some IC responses/comments expressing concern for vendor complications, due to the fact this set is shown in GMK and DCS. To clear up any confusion, the two kits are separate projects, they're just on one single IC to keep things simple. The two will run in the same timeframe as two SEPARATE group buy listings, meaning they will be produced - shipped - and delivered in conjunction with their own SP/GMK lead times.
*Everything I said above was said in the IC project description, please read it!*
If you want to purchase both GMK and DCS RGBY, you will essentially be joining two different group buys that will ship independently. I hope this helped, please notify me of any further questions you may have, thank you!
