Another new item now at SKDTac and you can get this set for US$65.00... "KYWI+ designated mag pouches were designed by PIG to expand the benefits of the Esstac KYWI design to multiple applications. The Esstac KYWI+ Triple M4 / Pistol Pouch is an offset pouch design that will allow you to customize how you want to carry your M4 magazines while providing pistol mag/utility pouches with positive velcro retention straps. 

SKD Tac has the EssTach M4 Pouch available... "This is without a doubt, the most innovative single M4 pouch available anywhere. Not only does it offer you a quick-draw bungee retention strap, and the ability to stack pouches via Molle/Malice interface, but the entire suspension system is adjustable/removeable, allowing for complete depth adjustment. Now a single pouch allows you options for complete retention, complete speed, and everywhere in between. You can remove the bungee and go topless as well.
