This is the Cylinder and Piston Set for the O.S. Max .21 VG.

FEATURES: Advanced Bi-Metallic Liner (ABL) cylinder liner construction
          This process uses a double layer of plating material rather than
            one thick layer. This helps the metal bond to the cylinder and is
            more durable. Also, the plating process is more consistent,
            resulting in a more precise fit between piston and sleeve
            for better compression and longer life
          Machined aluminum piston
