Jungle and Vest/chest rigs don’t mix well. You’ve got to go back to a more traditional patrol rig like the old ALICE System. That means you’ll need a belt mounted mag pouch. MRLC Designs has developed this concept for exactly that purpose. At this point, the materials are still under evaluation, but the basic concept is mostly there.
The Conceptual Jungle Utility Gear Suite (CJUGS) M4 Magazine Pouch is a modernized LC2 pouch that is PALS/MOLLE compatible.
The pouch holds three (3) M4 magazines, incorporates PALS webbing on the sides to facilitate the attachment of grenade pouches, etc. and has a D-Ring to mitigate load when used with the load carriage harness.
In addition, hook and loop closures which can be snagged by “wait-a-minute-vines” or become degraded in the jungle environment have been replaced by repairable side release buckles.
