There are different stocks available for the Uzi proper. There is a wooden stock with a metal buttplate that comes in three similar variations that was used by the IDF. The first version had a flat butt and straight comb and had hollows for a cleaning rod and gun oil bottle. The second had an angled butt and a straight comb and no hollows. The third had an angled butt and curved comb and no hollows; a polymer version is currently available from IMI. The wooden stocks originally had a quick-release base but the ones sold in the United States have a permanent base to be compliant with US gun laws.
