The V Seven Weapon Systems Enhanced Teflon Coated H3 Buffer is constructed from 7075 T6 Aluminum and then receives a durable industrial grade Teflon coating over a Type III hardcoat clear anodize. The construction of this H3 Buffer in conjunction with an improved bumper provides a softer feeling recoil. Internally lubricated for those wanting to reduce the sound from the buffer system. This buffer works great with the V Seven Weapon System carbine and rifle action springs that feature the same Teflon coating.
