He took on too many builds because he is making over 60.00 an hour on RPD's and the money looked good. However he screwed his customers because he was greedy. Let's face it, at $875 a pop he stood to gross $39,000 just off of the RPD builds. His overhead as a one man shop is very low. I know, I run a one man shop in the evening.
Hopefully he can lower the number of builds he is taking in, make his lead time more reasonable and be honest about it, and be successful. As a pro-second amendment person, I would like to see more and more people with FFL's, but we don't need more that make promises they can't keep which is unfortunately quite common among people who go from a hobby to a business. When he reduces his lead time, he'll have a more stable cash flow (instead of nothing for months then one giant lump sum), and business will be much less stressful for him.
