Based on the information I can find the 308/7.62x51 Pmag has never been made in any size, but 20rds. Is that correct? If not is there a good alternative in 5 or 10rd available? I looked at Larue and they don’t seem to have one either.
Try the link below. I have some 15 rounders and they work great. They also have 5 and 10 round mags.
