Need help with new SBR upper

[todd.k]

I'm not sure there is any debate, I've shot shot several rifles with two gas rings removed that functioned fine.

Now I'm quite curious to see if, on a new rifle with the bolt gas rings lined up, we can duplicate poor reliability. Although I'm sure at some point in its break in process, the ring alignment will have no bearing on the reliability of the rifle. I'll keep this in mind for when I build a new upper.
