I just zeroed my Tavor's BUIS and did it with a bullet tip. PITA, but it can be done. However, once done, it's done until you change ammo.
I was able to hit our 100m, 150m, 200m goings from prone just as well as with the red dot. Some good ol' boys shooting scoped rifles from the bench challenged me to go for the 400m gong with my remaining three rds. With them spotting, I went 2/3 with the iron sights. I'm awaiting cataract surgery for my right eye (left eye already done) so this was particularly gratifying.
