You must have missed this in the instruction manual that came with your Renegade builder set!!
I would strongly suggest everyone who builds one read the manual thoroughly.
I personally thought this was a step that I could skip as I have built several AR's. However I was mistaken!!
I missed the part about the gas rings as well, but saw the error of my ways BEFORE I made it to the range.
This specific issue is addressed on page 15 and is attached as follows
So yes, you need to remove the gas rings!
I hope that helps
