I have been using PSA uppers on AR-15 builds. However, when reading the specs on the PSA 7.62x39 uppers there is a note stating that they will not fit on a Mil-spec Ar-15 lower. I am looking for suggestions on a compatible upper in this chambering, or, learning if simple modifications will allow the pairing.
Some comments I have read seemed to indicate that reliable magazine feeding is the issue but that specific magazines eliminate that problem. Information on the best magazines and uppers to use in a 7.62x39 build would help me keep the project moving forward. Thanks for your help.
