This is a raised rear sight for the Elite Force PPQ airsoft replica. It is to be combined with one of our Tactical front sights for the PPQ. You can mix and match, they do not all need to be from the same type.
The polymer version will install without any modifications. The Metal ones will need to have the screw hole threading cleaned with a M2.5 x 0.45 pitch tap before install.
This is for airsoft use only and cannot be made to work with real firearms
