Journalists generally explain it poorly, but basically IDF decided to replace Tavor with M4. The only twist this time is, they don't want to rely on American supply in the face of the demands in Ukraine and other theaters, so they are going to make those ARs themselves.

I remember that a ton of articles were posted in 2021 about Tavor not going away. However, the 2022 SVO in Ukraine changed the calculus very much: a cheaper, easier to manufacture, effective rifle is called for.

There's no much wrong with Tavor except the cost, and let's face it: not being an AR is its greatest demerit.
