It is a sweet bullpup. It does have a few drawbacks though.
No last round bolt hold open. It needs to close to eject the last round out the front.
Odd feeling in the hands.
That being said, I would totally buy one. To me, it has less felt recoil than an AR. Ejects out the front so so hunting for brass if you do reload. Short OAL with a full 16" barrel and good balance. Plus if you are military, FN is doing a $300 rebate on the FS2000.
Another good option is a MSAR E4
