How's the gas port? An adjustable gas block is an easy way to tune a gun but that much pressure seems like some thing/things are out of spec. Mixing and matching parts maybe an issue. I understand needing a new receiver but I'd be looking at the barrel/block/buffer/ammo more than the receivers.
If I paid for something that I didn't get(especially at that price) I'd be looking for some or all of my money back.
