Curtton, do you ever sleep? The mags came with the rifle,except for the 5/30 rounder which I bought from killercane (nice guy to deal with as well). The 15 rounder (I thought they were 10s) had to have the latch and lips massage a bit with a file to fit and function properly.All the short mags are a pain to seat.Might be that the mag springs are compressed all the way making it difficult for the rounds to be pushed down when contacting the bottom of the bolt.They seat great when no rounds or less then 5 are used.
