Hey all, I'm looking to know if the 10 round magazine from the 10 FCP-SR will fit in a 12 LRP? I have the 12 LRP and would like another 10 round magazine. I have a Dark Eagle mag for it but want a cheaper alternative. The part that interfaces with the rifle looks the same as the 4 rounders and the Dark Eagle. I called Savage to confirm this and the lady was a little confused. She told me yes but there were specific 308 and 6.5CM mags.
So what gives? do they fit and are they worth the price?

My rifle is a model 12 LRP 6.5CM center feed top bolt release.
