I’m no expert but as far as a Tavor bullpup vs. M4/AR15 rifles i believe the barrel length is the same; the difference is simply pushing the action back farther closer to your face. I think muzzle velocity is the same. They even use the same magazines!

On most bullpups, yes. The one in question, if I am seeing it correctly, has a shorter barrel, though only by less than 1/2". My thinking is that with less friction, a shorter barrel should produce higher MV than a longer one. I did find an article that discussed the very issue and their results were quite surprising. Looks like it needs more research but the table below seems quite comprehensive.
