CMMG Buffer Assembly, Stainless Steel, AR15

The CMMG AR15 Buffer Assembly (brand part number 55CA9A7) is a stainless steel buffer built for AR-15 rifles with rifle-length receiver extensions. At roughly 5.4 ounces, it falls in the heavier, rifle-length buffer weight class, which many shooters prefer for smoother cycling and reduced felt recoil in a rifle-length gas system compared to a lighter carbine buffer. CMMG builds it to the same fit and function standards shooters expect from their AR-15 furniture.
