EOTech & magnifier works great for me - the OEM BUIS co-witness, and the height is JUST enough for me to be able to shoot it.
BUT, sight height is an issue - the struggle is real.
If I'm wearing gear or a sweater/thick jacket, I need to cant the rifle about 15 or 20 degrees left to get a cheekweld and sight alignment.
I can either run the EOTech and magnifier on a riser and lose co-witness (and have it look awkward), or run the Manticore rail and lose the BUIS.
Not sure which route I'm taking yet.
On a related note, although you require a VERY tall mount (no drawbacks to the Manticore rail here) - an LPVO is ideal for the Tavor7. Mainly because with 7.62, there's more capability for an LPVO to take advantage of - and the trigger is noticably better (not aware of any aftermarket solutions for the 7 yet).
With modern ballistics software and BDC reticles, it opens up a whole different level of bullpup performance.
