You are free to have your own opinion. But, you wording isn't very nice. I happen to like the looks of these bullpups. And, while you comments might be nicely received at another forum, this is the FN Forum. There are MANY fans here of the PS90 and FS2000, and fans of these 2 guns make up the larger bulk of our members here.
So, since you have nothing nice to say, maybe you should keep those comments to yourself.
Why do you say that? In making the current M4 into what it is, in my IMO they have gotten rid of most of the advantages that platform had. Are M4's they better than an AK? Yes, but that aint saying much. I'll take a 308 bullpup any day.
