The Half Flap is designed to increase carrying options with Spiritus Systems Pistol Magazine Inserts in the Micro Fight Chassis front pocket.
Installation is straightforward by attaching the Velcro strip between the magazine insert and the Chassis wall, then folding the Half Flap over the front pocket.
Compatible with Micro Fight Chest Rig MK2, MK3, and MK4 models, but not with the MK1 version.
