Israel has always had an “interesting” history when it comes to arms deals. They are clearly a friend of the US, but have sometimes done deals with countries that may not have always had US interests foremost in their minds. They also have a bit of a history in not always abiding by arms embargoes… most famously in the case of South Africa during the apartheid era.
One gun that has that semi-checkered history is the KSN Golan, which is a copy of the CZ99 Compact-G.
