What mags seem to be running good in the RPR. My Factory mags were a headache..always had rounds jam. I have one AR 10 PMag and feeds well but can't single feed due to it stopping the bolt, guess it can be done but is a PITA. The OAL of the PMAG doesn't allow for seating depths past factory spec. Suggestions? MDT mags are an option but are very short OAL.
