Production line? Come on. This is not Ford motor company churning out racks. Most of these companies maintain a small staff and build orders as they come through. I would gladly build my own rack, like I have in the past, but I don't have time. Im going to order from Beeger Boxes and wait for the shipping.
Actually those of us that produce products for public sale have many things set in place for production.
I wouldn't change my holster design for anyone, Why? because that's the way I do things.
Its not all about you, why change what works for the company?
