What is it? Its a grinding method to microscopically remove material from the surface of the bore. Using extremely fine diamond compounds, we can remove material from the inside of the barrel that is uniform and consistent throughout the bore. Leaving a mirror-like finish that's very time consuming to achieve on a steel barrel.
As a result, the following happens.
Below is an example of a Prometheus Barrel 6.03mm, pits, and bore marks can be seen within the barrel. With lab instruments we've measured this low/high spread as 5 microns. These microscopic holes tend to catch BB residues, and increase the internal friction of the barrel slowing down the BB.
Below is that same barrel with our lapping process done to it. We're able to reduce the internal bore surface roughness to below 0.5 micron. Resulting in a mesmerizing mirrored effect on the inside.
