Magpull Magazines
I've got two 20 round mags from Magpull and my Sig 556 doesn't like them at all. FTFs all day long. In fact the only magazine that has been flawless is the sig 30 rounder that came with it. It sounds like this is the exception rather than the rule. Anybody have an answer as to why these Pmags don't work? In most cases the missed round is still in the magazine slightly tilted upwards and its always the round on the left side that gives me an FTF. It seems that on the rearward movement of the bolt carrier, as it slides over the next round to be fed, it pushes the back of the case downward and it stays down allowing the bolt to miss it
