Wosport MK4 Chest Rig MP5 Magazine Insert — Ranger Green

The Wosport MK4 Magazine Insert is a magazine carrier insert designed for chest rigs compatible with the MK4 system, sized specifically for MP5 and compact submachine gun magazines. It provides an organised, modular solution for anyone wanting to configure their chest rig with dedicated SMG magazine cells, without resorting to universal pouches that compromise retention control.

Each cell is open-top with elastic retention: magazines go in and come out in a single motion, with no retention clips or buttons to operate. The advantage is speed of manipulation, even with gloves on. The trade-off is equally straightforward: elastic holds well in static conditions and accommodates dimensional variations between different magazine manufacturers, but offers less security against drops or sudden movement compared to a rigid snap retention. Anyone choosing this setup is prioritising fast access over absolute retention.

The insert integrates into the MK4 architecture, keeping the chest rig's compact profile without adding lateral bulk. Ranger Green pairs well with MultiCam Tropic, A-TACS FG and the green variants of the most common modular systems, sitting discreetly in woodland environments and in operational contexts with a cool colour palette.
