The Rainbird 1800 series pop-ups, as well as most others, are strictly the sprinkler body itself. The nozzles are seperate, and are installed in the sprinkler prior to installation. So, if you get the 1800 series, you can choose which ever nozzles you need, whether it be quarter, half, full, or adjustable. Don't forget to install the filter screen with your nozzles.
