Overview
This lapping compound is intended for final fitting work where a very close, smooth mechanical fit is needed, including semi-auto slides and frames, rifle bolts, and receiver raceways. It uses aluminum oxide abrasive crystals in a water-soluble base, which supports easier cleanup with soap and water after use. The #600 grit version offers a finer abrasive option for controlled lapping, while the rounded crystal shape is described as helping reduce the chance of particles embedding and continuing to wear the part after cleanup. It is supplied in a 4 fl. oz. jar.

Considerations & Trade-offs
- #600 grit is a fine abrasive, so it is intended for final fitting rather than for removing material quickly.
- The compound is sold as a single grit option; if a different level of aggressiveness is needed, the #800 version is a separate choice.
- Cleanup is water soluble, but that also means it is designed around soap-and-water removal rather than leaving a protective residue.
- This is a specialized lapping compound for close-fit mechanical work, so it is not a general-purpose abrasive for broad shop use.
