It looks like the Whiskey Two-Four Skirt with Belt Adapter is what just Booligan Airsoft needs for a lightweight rig... "A lightweight rig makes for a happy operator, especially for dudes like me who are carrying enough weight on their body in the first place. WTF's 'Skirt' has everything I would want for a low profile, lightweight belt based MOLLE rig!"
Limitless Gear announce the release of a belt adapter for the OPFOR MC-R Magazine Carrier. You can order this at their online store for US$5.00... "Rugged, flexible, and light weight the belt adapter for the OPFOR MC-R allows for direct mounting on belts up to 1.75-in wide."
