I just acquired a RAP in .204 with the factory AICS 10rd mag. Also purchased a Magpul American Hunter Stock for it. I heard of potential feed issues and saw this thread and wanted to verify the function prior to working on the change-over. Have you experienced any feed issues with the Magpul 223 AICS mags feeding the 204 RAP? And have you tried the AICS Ruger magthat the RAP came with in the Magpul stock/bottom metal? This is a great resource, thanks!
