Wosport MK4 Chest Rig Insert 40mm Grenade Pouch — Black

Grenade insert for 40 mm rounds, designed specifically for the Wosport MK4 chest rig. Three elastic loops hold up to three 40 mm grenades vertically in an immediately accessible position. Built for operators running light offensive loadouts who want to centralise their kit on the chest without adding dead weight.

The elastic loop system is the right choice when the priority is speed of draw and re-stow: a grenade goes in and comes out with a single clean motion, no buttons or retention devices to operate. The trade-off is that retention relies on elastic tension rather than a positive mechanism, so under hard movement or in a fall the grenades are less secure than in a snap-closure pouch. Those working in dynamic but controlled conditions will find the compromise acceptable; anyone expecting frequent rolls or prolonged inverted positions should consider a solution with active retention.

The modular design allows this insert to be combined with other inserts in the MK4 line, letting you adapt the rig configuration to operational requirements without replacing the entire system. The construction is purpose-made to fit inside the MK4 with no play, keeping all inserts stable under load.

Key points

• Three elastic loops hold up to three 40 mm grenades for quick, one-motion extraction with no fasteners to operate.
• The elastic system allows immediate one-handed re-stow, well suited to fast firing sequences.
• Native modularity with the MK4 system: pairs with other Wosport inserts to build the configuration that fits the role.
• Loop retention: strong for speed of access, less suitable where a risk of drops or prolonged inverted positions is expected.
• Purpose-built to seat inside the MK4 with no slop or shift during movement.
