That and the Tavor is slowly replacing them... But I still like them.
However, unlike in the case of the IMI Negev, the IDF standard issued 5.56 mm Light Machine Gun (LMG), the IMI produced the TAR without a signed agreement with the IDF, which doesn't really need or want the new weapon, especially since the M16 assault rifle and its various carbines variants can be bought at very low price via the U.S. Foreign Military Support (FMS) funds.
The TAR recently finished its last field tests in the IDF Golany infantry brigade. However, due to the budgetary reasons mentioned above, as well as the lack of any actual need for such a new assault rifle, it's very unlikely that the TAR will actually be adopted by the IDF, unless the IDF will be forced to do so by a strong political domestic pressure, like happened with another IMI product - the Negev LMG, which is to an extent a clone of the FN Minimi (M249).
The M96 is essentially a semi-auto version of a SAW.
