I am building my first AR and have completed my lower. I bought my stripped upper from PSA, but I'm not sure where to go from here. I saw lower build kits everywhere. It seems you have to buy all the upper parts individually. The problem, is that I don't know what parts to buy. Can anyone post an upper parts list for me?
Also, what parts will give me the best value? Thanks |

so you want to buy all the tools needed or do you have them all ready? if not you can find great deals on complete uppers here on the EE. unless you plan on building more, in the future?
if you are building a regular forearmed upper....... upper delta ring assembly barrel nut barrel gas tube roll pin for gas tube front sight base(FSB) correct sized forearm set and the complete bolt control group(BCG) all sized up for a carbine,midlength or rifle gas system. |

If he bought a truly stripped upper, he'll also need a forward assist/FA spring/FA roll pin.

Just to clarify for the OP, you will need the charging handle as part of the complete BCG. |

Brownells sells upper parts kits. They offer them made by a few different manufacturers. I am sure they are cheaper than buying each piece on its own. |
