| New build and I have about 600rnds through it but sometimes when I put a new mag it won't chamber the first round, doesn't matter if I pull charging handle or hit bolt catch. Does it with gen 2 30rnd pmags, gen 3 30rnd pmags, gen 3 10rnd pmags. It doesn't even catch the bullet at all when it happens, I just rack it and click no shot and no bullet in chamber and then I rack again and boom goes off. Once the first round is racked it shoots flawlessly, it's just every once in awhile it happens not every time. Any help would be appreciated! |

you are not pulling the charging Handel back far enough might be a buffer problem but more likely you are not pulling it back all the way. new rifles often go back & tense up but if you really pull hard it will come back an extra 1/4 inch
I have a very bad injury to my support hand and have had similar problems to solve it I put in an empty mag, pull the charging handle back until the mag follower locks the bolt to the rear . Then drop the empty mag insert a full mag & slap the bolt release. |

It's not an issue of not pulling the charging handle back all the way, my first ar I was having that issue so now I make sure I do so. It has done it more times with the bolt locked back and me pressing bolt release after a mag change then it has with just racking by "sling shotting" charging handle so that is another reason I don't believe it's me not pulling charging handle back far enough. |
| Were they brand new mags? I had that happen when I put new followers in my mag. I do have a magpul 10 rounder that I don't think it happened with. But sometimes the first round out of a brand new mag will do that. If it keeps happening with the first round, I'd be a little concerned. But you could also try and lock the bolt back and then let it go on the first round. It seems like it has a bit more force than doing the charging handle. Sometimes. |

It doesn't happen every time, once in awhile. What I'm saying is that it happens both when I lock bolt back and also when I "sling shot" charging handle but actually has happened more when locking bolt and then hitting bolt release. Sucks when you go through 30rnds and reload quick and hit bolt release and all you hear is click after pulling trigger. Out of 600rnds it has happened about 10 times. |

Some people claim it can't happen, but I have seen it happen on more than one occasion. When a 30 round mag has been loaded to full capacity, the bolt can slide right over the top round because of the amount of tension on the follower spring. The times I saw this happen was with new rifles and new magazines. And yes, the magazines were firmly seated. |

It did happen twice with a 10rnd but that could of been a fluke bc I didn't have a problem with it any other time, the 30 rounders is what is giving me the problems. I'll have to mark mags and see if it's one or multiple, Idk why I didn't think about doing that before. |

I never experienced this with a PMAG but I have experienced it with a USGI mag. If the OP is using 4 mags for 600 rounds, that means each mag is being used only 5 times, which might mean the springs still need to be "worn in" a little. I found the best way to load the magazine is with a stripper clip. If you load one round at a time, be sure to "slap" it every 5 rounds to make sure it's seating correctly. Otherwise wouldn't hurt to top it off to 29. Old trench tales have soldiers always loading 29 rounds per magazine, especially if the magazine is rarely used. |

That's why I'd make a habit to top off at 28 rounds. |
