Just ordered the Dart Zone MK4X. If it's anything like the original, it will be a big win. I have recently installed a 1.9 x 350mm Spring into the original MK4 and it is scary powerful. Should be fun fight out of the box, but with a couple of upgrades it'll be shooting lasers!! One star reviews, for it not showing in stock at attempted time of purchase, are not a good indication of the overall quality of the blaster. Please order based on the continued quality and service provided by Dart Zone. Happy plinking!!
