"Thirty thousand lowers a week"
I dropped in on a customer today, to check the status of a quote we had in. We got to talking gun manufacturing (he is in the business, broadly (reloading equipment)). According to him there is a local company, about a mile from us, making 30K AR lowers, per week. Last I was in that place was about 10 years ago. At that time, I recall seeing AR parts and revolver frames, as rough forgings or castings.
