Wosport MK4 Chest Rig Insert 40mm Grenade Pouch — Coyote

The MK4 grenade insert is a modular three-loop pouch designed to hold 40 mm grenades and cylindrical objects of equivalent diameter. It is built to integrate directly into the Wosport MK4 chest rig, making the most of the front real estate without adding unnecessary bulk to the carry system.

The three fabric loops work through elastic compression: the grenade is inserted and drawn with a single vertical movement, no retention device to open. This makes it fast to use under stress or with gloves on. The trade-off is typical of open-top passive retention designs: access is immediate, but the grenade is not mechanically secured, so on sharp movements or falls the contents are less restrained than with a snap-lock or velcro-lidded pouch. For roles where speed of access matters more than absolute retention security, this is the right choice.

The modular design allows multiple inserts to be combined, or this element to be swapped out for other pouch types compatible with the MK4 system, letting you tailor the chest rig configuration to the task: carrying smoke grenades, signal flares, cylindrical torches, or quick-access recovery gear.
