Compatibility and part identification

Small differences in platform, caliber, configuration, production generation, dimensions, or part number can affect compatibility. Confirm the complete firearm model and manufacturer part reference before treating components as interchangeable. Complete platforms and upper-receiver-kit references are organized under HK Rifles. Handgun components are listed separately under Handgun Parts.

Professional service and safety

This catalog is provided for identification and educational reference and does not contain installation or firearm-modification instructions. Keep firearms unloaded and physically separated from ammunition during inspection. Components affecting firing, locking, pressure containment, or safety systems should be inspected and serviced by a qualified gunsmith using the manufacturer’s procedures. Never remove, disable, or bypass a safety feature, and follow all applicable laws.
