Wilde Built Tactical custom makes these panels to your dimensions. The panels feature full coverage with MOLLE webbing. They are made from 1000D nylon with a Velcro backing and grommets if you choose to mount the panel with screws.
If you are like me, and already have a ton of MOLLE pouches laying around, this can help you organize both the pouches and the small gear that tends to clutter your gun safe.
