Gunbroker has a real funny search feature. Searching for complete uppers I found like 7 different way to type it into the search and found more each time. The lowers are the same way
You are right on the lowers on Gb though. They can be found locally for about 350 on armslist.
Also, grabagun sold out in less than 9 minutes
Here's some stripped lowers in stock for $260http://www.surplusammo.com/saa-sa-15-grim-reaper-ar15-stripped-lower-receiver/
