The Micro Fight Chest Rig Mk4 is designed to be extremely efficient, modular, and lightweight. The Micro Fight works seamlessly with Spiritus Systems accessories suite, which offers nearly endless configurations. The Micro Fight features soft loop Velcro in both pockets to enable you to put mission essential items where you want them based on your individual needs. The improved profile allows for the use of six 5.56 x .45 style magazines or four 7.62 x .51 magazines or any combination of rifle and pistol magazines. The 5” x 9” field of hard loop Velcro on the back of the rig allows for solid integration with accessories, such as the SACK Pouch or Expander Wings.
