**AR45 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 email@example.com and we'll help right away!
