As does Kibler for his production.
I can point to my area of employment as a good example of the same dynamic. My company holds maybe 12 percent of the North American market. The small handful of other companies combined building the same type of product enjoy the other 88 percent. They of course for various reasons build more product combined than we do. They are the bigger fish, we are small fish. They get parts from the same parts suppliers LONG before we do, BECAUSE their invoices yield higher dollars to the bottom line.
In the traditional gun parts market, outfits like Chambers and Kibler are the big fish, and the regular gunsmith or DIY guy is the puny small fish. Who do you think will enjoy the lion's share of available parts, and who do you think will struggle even finding any?
