Parkerizing is a real dull grey or black. Its what all the M1 garands used to have. Its twice as durable as blueing (supposely). You see them on alot of tactical rifles. There are only a few people around my place that do it. For a professional job, find a gunsmith that will do it. Most places that specialize in tephlon does the same for parkerizing.

It will or can chip like tephlon in a skillet.
