BROWNELLS - Silicon Carbide Abrasive Compound #600 Grit

This was purchased to replace my now-empty tin of this abrasive. I use it occasionally, as I have the full selection of grades, and some grades have specific uses than others cannot do. This is 180 grit, about the coarsest usable for fine work. . I use it for everything from fire-lapping to barrel crown touch up. Since the original tin was from the early 1980s and was just recently consumed, I should have enough for quite some time.

Use CLP aerosol to clean it up with brass brush not to make any small scratches. Also USE ONLY WITH STEEL not aluminum or any other metals like the last review stated. It will eat trough that AR and ruin that bolt now!! Lmfao. The best thing about it is using it after welding and a brass brush to get that perfect fit. Even in other job take underwater and apply to certain areas for things that make MN lives better without them knowing. Special trick . Use wrong kind and you know that is why a few grains on blueprinting a new bolt action bolt lug to mating face until all same color then your good. I mean half a m&m size most times. Just make sure to clean parts in sonic cleaner or with CLP then into a tumbler.

Used this stuff to lap my AR receiver. It worked great.
