The CMMG AR15 Buffer Assembly (brand part number 55CA977) is a carbine-length buffer built for AR-15 carbine buffer tubes and stocks. Weighing in at roughly 3.1 ounces, it sits squarely in the standard carbine buffer weight range, giving reliable cycling in a typical carbine-length gas system without the guesswork of an unmarked replacement part. CMMG finishes the buffer in silver and builds it to the same fit and function shooters expect from their AR-15 furniture.
