OK, quick and dirty, here's the dump.
I have recently updated and modified the "low profile" chest rig design, which sports single, open-top mag pouches, with kydex inserts. I have always liked this design for a pure gun-fighting rig.
The basic or "classic" rig was called the "Alleycat" by some, as play on the original "Hellcat" design by SOTech. With input from Hawkeye and others, this rig is now called the "Minuteman", which I think more closely describes it's purpose, for us as armed civilians. It is designed to be a grab n go rig, much in the same way our forefathers grabbed their powder horns and possibles bags.
The "Minuteman" comes with many different options, but it will always have an open back, as in no lumbar panel.
Here's a basic, solid front 4 mag rig.
Here's a 6-mag, spit front rig with "X" harness. Note open back.
As this rig evolved, another purpose emerged, which was an extended wear version, for training or patrolling. In keeping with our Patriot theme, this one was called the "Swampfox". It is a full wrap-around design for carrying additional gear for extended ops.
The "Swampfox" also comes with different options, but it will always have a lumbar panel, and wrap around fully, like a battle belt.
This particular rig has 4 mags. Note lumbar panel.
As for options, let's start with the "Minuteman". The basic rig has a solid front and cross shoulder straps. It can be made with 3-6 mag pouches per customer request. It can have 0-4 side slots for additional pouches. It can even be made with just a PALS grid. And yes, it can be cut for "universal" pouches, which will fit both M-4 and AK mags.
Next you can upgrade the shoulder harness. The "H" harness adds a cross bar between the shoulder straps, which as the name suggests, resembles a big letter "H". It is a bit more comfortable than cross straps, although you now have to un-do a diagonal, as well as the back strap to get into the rig.
The "X" Harness is another step up. It adds a small, lightly padded cordura panel, for hanging a hydro pouch on. It resembles a spider or big letter "X". It is the most comfortable but also requires un-doing a diagonal strap along with the back strap.
Enter the split front. Originally designed for extreme hot weather use, the split front allows you to put the rig on like a vest, which is very useful if you have a "H" or "X" harness. It is now essentially an up-dated LBV, so we can also use low-profile (read more comfortable) hardware in back, instead of SR buckles.
So you can have anything from a simple 4-mag rig with solid front and cross straps, to a 6-mag rig with split front and "X" panel, which brings us to the next step.
The "Swampfox" is the logical conclusion to the design for extended wear. It comes standard with a split front, and a "X" harness. The side panels are extended and join in the back with shock cord (although for heavier loads, you could run paracord). This gives you some adjustment and expansion, much like an armor carrier. These are anchored and covered by a lumbar panel. With this lumbar panel you now have a full wrap-around design. But due to this design, you cannot have a solid front. But you can have 4-6 mags, or plain PALS grid, on the side panels. And I guess you could run a "H" harness if you wanted.
The last thing I should mention is colors. I can do coyote (or khaki) tan, ranger green, OD green, foliage green, black, PD blue, or Multi-Cam. I am also experimenting with coyote brown.
