The PWS Enhanced Steel Body Buffer in the Carbine H2 .308 Short configuration is a 4.1-ounce buffer for .308 applications (PWS part no. 5PWSCB30-1F). Primary Weapons Systems shortens the buffer so it works with AR-10 platforms that use standard buffer tubes. The same buffer ships installed in the company’s MK2 series complete lowers and rifles, so it is the weight PWS tunes those rifles around. It is a direct replacement for owners who want to restore or match the factory setup in an AR-10 pattern rifle.
