1 review for Lightweight SR25 .308 AR-10 Upper Receiver Billet

  1. Darren E. (verified owner)

    Disappointed that the skeleton lower and upper don’t match like the images suggest they do. Needed more deburing before anodizing. Excessive and rough tool marks visible through anodize. Several pocket defect from tool entry/exit.

    • ADR-15 (store manager)

      Darren had purchased his SR25 Lowers before the Upper and Rcvr Sets were made available, so the Rcvr Sets do match just as the current product pics show. And we’re not sure what the deal is with tooling marks after coatings. Dan – machinist
