I found a neat way to query Brownells for AR-15 parts categories. The content below will display Bolt Carriers and associated parts and tools available at Brownells. This is neat for a few reasons. First the page is live and automatically updates so any new parts will be visible. The other nice feature is Brownells often categorizes parts incorrectly. This format seems to work better than their own site. Check it out and watch it for updates.
Additionally I might add other pages of specific parts.
