Upper Assembly: Any DPMS Generation 1 upper (e.g., CMMG, Aero Precision, Fulton Armory, and DPMS). We have found that the CMMG MK3 uppers fit best with our lowers.

Lower Parts Kit: Due to the varying quality and compatibility of .308 (AR-10) builds, we recommend using CMMG’s MK3 .308 LPKs, especially their bolt catch.
