After seeing a FS2000 at the LAV class in October, I decided to get one for myself. Since this is a bullpup style rifle, the OAL lenghth of FS2000 with 17.4" bbl is less than that of a 16" AR with collapsed stock. It is very handy and maneuvrable. I have the tactical version which comes with a full length rail. I promptly mounted Aimpoint ML2 in a ADM standard mount. I found the mount a little too high. I currently have 4" sight height. With a 100 yard zero, I have to aim 2.5" high at 25 yards. I will be going to a lower mount soon. The ergonomics of the rifle are nice, although the manual of arms is very different from AR. It lacks both bolt hold open and drop free magazines. However, the magazine release button is such, that it is easy to depress it while yanking the magazine out. After racking the charging handle, the rifle is ready for action. When disassembling it, I noticed a lot of small parts/levers/springs. I was hoping for something along the elegant design of an AR or AK. But that's a compromise I'm willing to take. Another benefit of this rifle for AWB states is that it is designed to accept standard AR magazines, and we are not hamstrung ala PS90. I also got lucky enought to find the new FN tri rail online and install it. I definitely like the feel of the rifle with a VFG installed, plus it gives me the opportunity to mount a light. No rifle is complete without a sling. I used urban-ert butt stock adapter and mounted VCAS sling to it, with the front connected to the front sling mount via a mash hook. I don't like the front mount as I feel it interferes with access to the charging handle. I will be getting a rail mounted sling loop soon and moving the front sling attachment point to the rear of the rail. Shooting FS2000 is pleasant. The ergonomics are nice, and I find the safety is fairly easy to manipulate as well. I shoot about 120 rounds of Wolf and all fed without any problems. The ejection system means you won't be bother your neighbors with flying brass. I did not try to see how accurate the rifle was. Overall, it is a unique weapon which, as a gentelman from LAV class said, has a purpose as a CQB rifle. It will take some getting used since the manual of arms is very different from AR.
