You need to purchase a SRAM 10 speed rear derailleur, either an X7, X9 or X0. Your options are limited as SRAM and Shimano rear derailleurs/shifters are not compatible. There are still many SRAM 10 speed derailleurs available. The SRAM GX is an 11 speed groupset and not compatible with a 10 speed drivetrain.
