I have the 7.62x39 extractor, just tried the 5.56 to see if it made any difference. Still didn't. So I still have 6.5 grendel that I am fighting cycling issues. I feel like its the chamber since the upper portion of the case is scratched/dull from the previous pictures which I feel could cause an issue once things heat up and start constricting.
