In order to build a complete rifle, pair this complete upper with our AR9 9mm 80 Percent Lower Receiver, our AR9 9mm Lower Parts Kit and our AR9 9mm Buttstock Assembly.  With all four pieces, you will have everything you need for a complete build!

**AR9 builds are known to having feeding/chambering issues.  This is due to the buffer/spring combination people are using in their buttstock assembly.  We have tested our buttstock assembly to ensure our buffer weight/spring tension works with our uppers and are confident in our builds.  As always, if you have any questions or issues, email us at support@ghostguns.com and we'll help right away!
