To install, remove your front sight retaining pin, it is not necessary to remove the sight itself. Be sure to align the bushings retaining pin groove with the slides retaining pin groove. We suggest using a soft block of wood to drive the bushing until it seats on the bushing flange. NOTE: the bushing will only fit the CZ Tactical Sport with a barrel OD of .550″.
An alternate method is to freeze the bushing, which will shrink the OD, then install in the slide. Be sure and check the bushings ID fit on your barrel before installation to ensure a proper fit. Any questions contact CGW for tech support.
