    Well finished this project.

    I got it shooting at about 260 fps right now.
    I modified the valve to feed both barrels running a green valve spring on a red hammer spring.
    Reg set at 600 psi. barrel to paint match helps.

    With a bit more tuning you can get to 270 to 280.

    A update on the Ma-Deuce-A II.
    I did some tuning on it a bit.
    I put a blue valve spring in it.
    Still ran the red hammer spring.
    Up the reg pressure to 650 psi.

    I used a Python barrel kit to match to paint.
    Chronograph to 288, 289, 300, 285, 287, 286, 288, 285.
    Not bad for off the bench.
