This CMMG buffer assembly (brand part no. 55CA92C) is an H2-weight steel buffer for the AR-15 platform, adding mass over a standard carbine buffer to help tune cycling on builds running an adjustable gas block, a suppressor, or other conditions that push extra gas into the system. Swapping in a heavier buffer is a common, low-cost way to smooth out a rifle’s recoil impulse without changing the gas system itself. This AR buffer system part cannot ship directly to California.
