Back in the 1990s, Black Hawk Industries introduced this innovative chest rig. There are four individual pouches which will contain the magazines securely by Velcro. Each pouch will hold three M-16, three AK-17, or two M-14 magazines. The pouch flaps are very unique. They can be folded and adjusted for different types of magazines. The rig was used by US Navy SEALs in the 1990s and during Desert Strom.
