Rock Island slides are extruded
Really? I like to learn new things, but would have assumed they were machined from rolled preheat treated rectangular barstock. I'd need to see the material to believe they were extruded, there is a huge difference between rolled and extruded as extrusion is normally done with the more plastic materials like aluminum alloys. I know the RIA slides are 4140 assuming the ads are true.
