Yeah, now they're on par with the M16A0. :-P
They still have problems that cannot be solved without replacing the receivers. And if you're going to do that, you might as well replace the entire rifle.
I'm not really sold on the idea of a bullpup rifle in the first place, so I agree with you that they could have done much better. It's surprising however that they managed to so thoroughly mess up an AR18 based weapon, given that it is generally an extremely reliable design.
