CMMG Rifle Uppers for Sale

CMMG, Inc. of the United States has made AR-pattern rifle upper receiver groups since 2002 and continues to offer complete or stripped, often build-to-order, uppers across its RESOLUTE, ENDEAVOR, BANSHEE, and bufferless DISSENT lines. Its rifle uppers are defined by CMMG’s Radial Delayed Blowback pistol-caliber designs that reduce reciprocating mass and recoil while enabling 9mm, .45 ACP, 10mm, and 5.7x28 in AR builds, plus bufferless DISSENT uppers with the Compact Action housed in the upper, cross-platform magazine options, and recent fixed-ejector updates.
