What recourse would you have with Ruger if the magazine(s) you self supplied for their rifle did not work properly with the rifle?
As I understand it, one of the unique features of the rifle is the ability to take many types of 308/7.62 mags. So at a minimum you could use M1A/M14 mags, AR10 mags, AI, etc. Unfortunately these would be limited to 5 rounds rather than the 10 rounds of the mag supplied but at least they available and most are relatively cheap.
