I bought my upper from Stag which is located in CT. They originally sent me a non compliant upper and when I called them, I had the compliant upper overnight. Can't say enough good things about Stag customer service.
The only problem is why can't we have bayo lugs?
Because stabbing someone with a knife on the end of the gun when you could have shot them is inhumane, reckless, and borderline Republican. Those are all evil things in this part of the country.
