Just listened to the podcast and paid attention enough to catch the part about the gunbroker guy.  Same thing happened to me over a Vltor extended buffer tube with spring and buffer.  When it came time to pay he informed me he only had the tube and not the spring and buffer.  When I got it I learned it's useless unless you have he spring and buffer they sell.  Did this guy happen to live in Manhattan, Kansas?  They only charged me for what they had in stock, but it was still useless and will stay that way until Vltor releases more parts.
