Yes could be 5th, 6th, or 7th round.

Have heard that some of the CMP 3 clips have heavy park. Might be a good idea to take some steel wool on the outside lugs of the clips. USGI clips are best, like SA, IS, etc.

I think your spring is good to go.

Gas plug loose will not cause this problem, but would cause short stroking. Keep the plug as tight as you can. A 1/4 inch socket extension fits nice, and you can tighten it up tight. Don't be afraid to snug it up.

My guess is clips.

I have had rifles that after looking at everything else, that needed a new clip latch spring. For some reason your clip is releasing early and moving up.

It is either the clips, lack of lube, or clip latch spring. My bet is clips.

Could be the clip latch spring, if the en bloc is moving out of the rifle when you have the stoppage.
