I have 2 Tavor's One is the IAI version with the original Meprolight, I have an Aimpoint M4 with magnifier on the other.
For a shorter range rifle I think the original multi-luminated Meprolight is pretty darn good but realistically I think any quality red dot sight would be suitable. Maybe a low powered optic too but IMHO Tavor's are closer in quick handling, quick reaction rifles so a Red Dot with a quick acquired dot or chevron is optimum.
On the original versions the Geisselle trigger and trigger bow are an ENORMOUS change! Went from a 9-11 lb creepy trigger to a crisp match grade trigger. HIGHLY RECOMMENDED!
Just FWIW my IAI version Tavor I also have the original magnifier. Don't waste your money unless you are a collector. It's hard to not get wacked in the forehead every shot as the eye relief is short. Buy the railed version if you want to run a magnified optic.........
Remember, this is all supposed to be for fun...................
