This is a compensator/thread protector for the KWA USP. It is pre-threaded for 14mm negative/counterclockwise threads. It seats firmly but there are two holes on either side of the compensator for you to install two m4x5 grub screws. These grub screws will make sure the compensator does not rotate during play. This gives your airsoft replica USP a very aggressive look. It will definitely be noticed on the airsoft field
This is for airsoft use only and cannot be made to work with real firearms.
