I have a strange question. I was looking in the barrel of my SIG MK25 the other day and it appeared that some of the lands were raised a bit more than others. Does anyone know if this may be the case or am I imagining it? Has anyone else noticed this?
The lands are not raised, the grooves are cut. It is possible that some kind of manufacturing error cut some grooves deeper than others, but it is VERY unlikely. I think it is a trick of the light and shadow as you look down the barrel.
