This is the kit to replace the clip and or hardware on the D2 and Aluminum Dagger sheath. (Single Molle Sheath) If you have lost your hardware or bent your clip this is your answer. When re-installing the hardware we recommend using a small amount of lok tite to secure the screws so they wont come out. We do not do that from the factory cause many people take the clip off for permeant mount on molle. The brass pieces on the back are just retainers and serve only to keep the hardware in place until you install them.. The hardware takes a T-6 (Torx #6) to install, be gentle with micro hardware its easy to strip.
