Since Rudy at Macon Armory was able to build me a new 45 barrel I now have an extra complete 45 acp (Olympic Arms style) upper that I really don't need
I'm going to be listing it on Gunbroker soon along with 2 17 round factory magazines.
PM if you might like to get more info
this upper will work with any standard 223 lower--its not like a 45 glock lower-- its not a flat top upper but you could use it as a template to create the upper
