| Would appreciate some advice on selecting a reasonable low-end upper receiver. |

Are you talking about stripped or a pre-built upper?
Palmetto will be the one most commonly recommended with their PTAC line. I've seen a few minor issues with them, twisted receive lugs, weak weld springs in the delta ring, etc. There's usually no coating inside the bores of budget barrels. Nitride is ok if you can find one. JSE Surplus has uppers as well. Years ago I bought one and it was 100% reliable, however, they dremeled in feed ramps on the receiver to match the barrel's. Once I changed the barrel the upper was useless. Alpha Shooting Sports, use at your own risk. The only time I've had a barrel actually come loose from the extension was here
