Not sure where you get your info from but worldwide the tavor is widely considered a hunk of junk – and so are it’s clones. The Black Rifle will remain, but with a more powerful calibre still in research. It’s just too easy and comfortable to shoot, and with the 416 plunger it’s reliable. The only bullpups that are worth their weigh in gold are the AUG and the P90. The ‘plastic revoution’ has had very little influence on rifles compared to handguns. And most of the plastic ones (most of which I’ve owned or tried) are junk.
