I have several of the Tactical Taylor rigs. They work great. I love the open top single mag pouches. I have both styles on my current rig.
The only 308 mag the Tactical Taylor singles have trouble with are H&K G3 magazines, I had to rig a plastic sleeve inside to get them to come out easily and even then I had to fight them. PMags, M14, FAL and SCAR magazines are good to go.
Sucks Im not stationed in WA anymore, I lived less then 5 mins from Tactical Tailor, I used to always go over and check out the stuff. It was pretty cool because they have a window where you can see the ladies making the pouches and bags and what not
One really cool thing they sell are magnetic pistol pouches. You can run a couple 1911 mags or just about any double stack. Probably wont work with a FiveSeveN though. MOLLE Universal Pistol Mag Enhanced
