So for an update… I dropped the upper off last Saturday and he called me Sunday saying he could find anything out of the ordinary other than the bolt didn't drop easily into battery. It was somehow binding on the gas tube. New gas tube and the bolt moves as smooth as glass. However I went and shot it today and it extracted 0 out of 13 rounds.
The most frustrating thing is I can't replace these rounds I'm shooting right now. And I'm not enjoying shooting them bc the gun isn't working properly.
So where do I go from here? Replace the extractor? Heavier buffer? One of those extractor upgrade kits?
Parker, if I were I am your shoes, I'd quit wasting my time with a problem child and request a refund. This guy apparently isn't knowledgeable enough to figure out what the problem is and shouldn't be assembling guns for sale. What ever came of the barrel extension issue?
