Brick Posted May 11, 2021 Report Share Posted May 11, 2021 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.

Not a shocker. We've reported here about PSA PA-10 uppers NOT fitting on other lower receivers. It's all in the history here, and searchable. PSA is proprietary. To PSA. Only.
