I went with the M21 for my Tavor in the end, I liked how it did not need batteries, and figured since they did such a good job on the rifle, they cannot be too far off with their choice of optic. I have been happy so far with my choice, and the washout remover seems to work well as I have not experienced any wash out issues, although admittedly I have not gotten it out as much as I would have liked since adding the M21 optic.
