There’s a few videos on YouTube about updating these old surplus rigs that make them work a bit better.
https://www.venturesurplus.com/products/army-multicam-tactical-assault-panel/I’m using a Blue Force Gear Ten Speed chest rig but set up for night hunting. I really didn’t think I’d like it but after searching for a battery in a pocket in the dark I realized I needed better organization.
It holds 4 magazines but has 3 columns of molle on each side to attach more pouches if needed.
I carry 2 20 round AR mags and have a water bottle pouch in one mag pouch, this holds my thermal scanner. Two pistol mag pouches attached to the left side and a small GP pouch on the right side holds extra batteries. I have a red light clipped into one column of molle for when I need it. The admin pocket is built in and perfect for a couple of calls and my NFA paperwork.
