Follow-up: I went with a Bear Creek Arsenal side charger and it fits! The side charge is awesome!

I am looking for a complete AR-10 Upper that is known to mate with the Polymer80 Warrhogg lower. Polymer80 support just says get one that is DPMS compatible. I went to Palmetto State Armory and tried one of theirs which is supposed to be DPMS Compatible. It doesn't fit. Saw two users here mention the Aero Precision upper, but they don't sell a complete upper, just a stripped one. Anyone have experience with a compatible complete upper? Thanks.
