  • .55AX ABL 40K E3071

    Features

    Same mounting dimensions as the O.S. Max .46 AXII
    Advanced Bi-Metallic Liner process uses a double layer of plating
    material rather than one thick layer. This helps the metal bond to
    the cylinder and makes the plating 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.
    Angular head design offers increased surface area for better cooling
    40K Carburetor with diagonally placed needle valve eliminating remote
    needle valve placement
    Two year limited warranty through Hobby Services beginning at date of
