I designed and had these two Bags made recently. They will probably be available commercially soon. One Gear maker wants to sell the Weapons Bag. The Weapons Bag is just long enough to hold a 16" M4. The other Bag is a variation of the Spartan Bag. I spoke with the maker of the Spartan and he said he might start making them like this. He knows I made a variation of his Bag. I can't and will not sell these. The biggest modification is removing the Admin pouches and making the whole inside Mollee. The user can attach what ever Pouches he wants this way.
Here are the main features and Mods for the Weapons Bag.
1. Just long enough to hold an assembled 16" M4.
2. A slit covered with a Velcro Flap was cut into the side. This allows you to carry a longer Weapon. Not to shoot out of
But for Range, non discrete use.
3. Elastic keepers run along the interior side walls. They are sized to hold, M4 Mags, Pistol Mags and Shot Shells.
4. Hole on top for drinking tube or Antenna.
5. Loops on the outside corners so it doesn't Sag when hanging up.
6. This one doesn't have the Elastic Cinch Cord on the interior bottom. But the new ones Will.
