Hey all,
I just bought an M400 about 3 weeks ago. I took it home, stripped it, and cleaned off the factory lube and replaced it with my own CLP. I took it to the range today and fired about 250 rounds, no mag dumps, or anything strenuous. The gun ran great all throughout. When I took it apart later to clean it, I noticed a large gap in the gas rings on the bolt assembly, and realized it was indeed blown apart slightly. I didn't find any splintering or anything crazy, and the barrel is fine.
My question is; is it common that these gas rings on a brand new AR to fail so quickly? Does this stem from a deeper issue? I called my gun shop and asked them if this is common, and they said it is, but I am military, and these rifles that we shoot are abused and have had many many rounds through them and I've never seen these gas rings break before.
