I can say I did it with a Tavor 7 without switching it to left hand ejection. And I paid for it shortly after, the brass was hitting me in the chin, but it was so fast I did not notice till after that the brass not only hit my chin it burned circles into it as they did. At least with that one it can be switched to lefty without buying anything extra, unlike the X95 where you have to buy a lefty bolt to do so
