The CP aluminum 30s with MP followers and CS springs, and the Marlube finish are $9.99. I bought 25 and have run about 60 rounds through each of mine without any problems. For $9.99 (44mag) they are a deal. I have a few D&H and NHMTGs that are also without fault. I'll buy another 25 or so of the CPs before the new ban takes effect. The only SS mag I have is a straight 20 CP and after only 40 rounds it too is 100%. All my AR mags came from 44mag and are less than 4 mos old.
