Angstadt Arms Hydraulic Buffer Kit Features The Angstadt Arms Hydraulic Buffer Kit is built to smooth out the sharp recoil impulse that straight blowback pistol caliber carbines are known for. Weighing 6 ounces the buffer uses a standard damping profile tuned specifically for 9mm .40 S&W and .45 ACP chamberings performing best in primarily unsuppressed setups across barrels of all lengths. The buffer measures 4.35 inches extended and 3.90 inches when compressed a design that eliminates the need for an additional buffer spacer during installation. Hydraulic dampening inside the buffer absorbs the bolt carrier s impact at the rear of its travel reducing the harsh recoil pulse shooters typically feel with straight blowback systems. The kit ships complete with a carbine buffer spring giving the installer everything needed to complete the upgrade without sourcing a separate part. Finished in stainless steel with a black bumper the buffer is built to hold up to repeated cycling without excessive wear. This direct drop-in installation makes it a straightforward upgrade for PCC owners looking to improve felt recoil and shooting comfort on the range. For PCC shooters who want a smoother-shooting more controllable gun the Angstadt Arms Hydraulic Buffer Kit is available for sale at GrabAGun.
