Well that in itself is not a bad idea. I think the basic frame of the vest is pretty good, and for a general issue item the build quality is reasonable. With the following minor modifications it would be an ideal piece of gear:
- Remove the kidney pouches and bayonet.
- Place modular attachement points where the kidney pouches are, so C-9 pouches can be attached in their place.
- Replace the mag pouches with modular attachement points. so small pouches for M203, Grenades, PRR, pistol mags can be attached.
- Issue those extra pouchs, along with inserts for the C-9 pouches for M203 and C-7 mags
- Replace the torso straps with bungie cords, or ANYTHING that can actually be adjusted on the fly.
- Add a wide belt at the bottom.
- Grip pads on the shoulders
See? How hard could it be?
