The Angstadt Arms 6 oz 9mm Hydraulic Buffer Kit with heavy damping (brand part number AA09HBKSDP) smooths out the recoil impulse of a straight blowback pistol-caliber carbine. Angstadt Arms tunes the heavy damping profile for suppressed use or for unsuppressed barrels longer than 8 inches. The buffer is a 6 ounce hydraulic unit with a black bumper, and the kit includes a carbine buffer spring. Because the buffer is 4.35 inches long and compresses to 3.90 inches, no buffer spacer is needed.
