tjtorborg Posted August 9, 2011 Report Share Posted August 9, 2011 Hey guys,I recently got a deal on a complete Rock River lower. Do I have to stick with Rock River or can I use someone else's upper? Any and all advice is more than welcome.Thanks,Tom Quote Link to comment Share on other sites More sharing options...
98Z5V Posted August 10, 2011 Report Share Posted August 10, 2011 Only a Rock River, unless someone in the aftermarket started putting them out. I haven't seen an aftermarket upper receiver for one of these yet, but it might be out there. <dontknow> Quote Link to comment Share on other sites More sharing options...
Bryan Hoover Posted November 20, 2017 Report Share Posted November 20, 2017 Any new information on this? I just acquired a RRA complete lower and don’t care for the uppers they offer? What if any parts are interchangeable with other manufacturers? Quote Link to comment Share on other sites More sharing options...
