I kind of want one just because it kind of resembles a Tavor, but quite frankly there are much better options out there if you're not going to have multiple 12ga Bullpups.
Highly reccomend the FD12 which also accepts the AS46 10rd mags.... that's right. 10+1rds of 12ga in a Semi Auto... legally. The Specter can't do that as it takes proprietary mags.
Let me know if you pass on it, may be interested.
