Could be a gas system problem. Not operating properly therefore not chambering a round.

Could be a magazine problem. Try one of your saved USGI 20 or 30 round preban magazines instead of a 10 round commercial magazine that you are using for testing.

Check that the spaces in your gas rings aren't all lined up in a row.

Your gas block may not be aligned correctly over the gas hole in the barrel.

So how do you prevent and fix this problem?

What kind of gasblock do you have? Is it the standard fixed front sight that was alligned/pinned by the manufacturer? If so, look around where it is clamped to the barrel for soot indicating gas blow by. I had that issue once with a gasblock I had bought. I replaced it and the problem was solved. You could also verify the gastube is clear and the gasblock is alligned with the barrel hole by either blowing air with a compressor or shooting some WD40 down the tube, it should come out into the barrel. Also, verify the gas key is tight on the bcg. And that your gasrings (3) are installed and not damaged. It's a simple system when you think about it. Follow the path the gas takes from the barrel back to the bolt and you should be able to find the problem.

What ammo were you shooting and was your rifle properly lubed?

Perhaps your rifle still needs to break-in. Maybe you need to find a lighter buffer spring. Hard to say without more info.

Check the top of the magazine you were using, see if it is shiny or the park rubbed off. If so, your bolt carrier group is rubbing against your mag's feed lips. Try a different mag. If the spent case is being ejected and the mags are okay, you may just have to break it in. Good luck.
