I am going to chime in here because because I have done business with Clyde Armory on several occasions, both on the phone and in person. They are only an hour or so from me, so I guess you could call them local.
I have had nothing but good experiences with them. Everything purchased from them has always been as advertised, their sales team and customer service are stellar, and what's more, they do everything they can to get the basic civilian the same firearms/accessories that they market to LE. They are an LE dealer, and have an extremely high volume of sales for both firearms and NFA items, as well as accessories and ammunition. Even with all of that business, I have yet to see them screw up a deal that they didn't try to fix, and fix with the customer's desires as top priority.
The problem you describe does not accurately represent the CA I know.
