Abdomen MOLLE panel which attaches under the cummerbund flaps of most plate carriers. Opens at the bottom via Velcro to insert a stiffener and prevent flopping (cardboard is a stand-in until I find some suitable plastic to use).
This guy wanted a different attachment system (Tyr style as opposed to the snaps).
If I haven't answered anyone's PM's, don't take it personally... I've been getting an aweful lot of contact lately so it's hard to keep track. I've been trying to build up a stock but all I have now are 2 of the 9mm.
