WST MK4 Chest Rig Expansion Chassis II – Ranger Green

WoSporT MK4 Expansion Chassis II side expansion
WoSporT MK4 side expansion is designed to increase the capacity and stability of your MK4 chest rig without unnecessary bulk. The entire panel attaches via VELCRO to the rear side and is then secured with side buckles, ensuring a firm fit on the body. On the inner side, you will find integrated pouches suitable for items such as a PRC-152 radio, while the outer plastic panel features MOLLE webbing for additional gear attachment. Thanks to its slim profile, the setup remains compact while significantly improving modularity. The expansion also helps distribute weight more evenly and stabilizes the chest rig during movement.
