    How hard/easy is it to change the ribs on the Max TA guns? Say I want to switch from the high ribs to the low profile max ribs. The O/U looks simple enough, but what about the un-single?Thanks.

    Piece of cake.

    Remove the barrel plug (false upper barrel plug) using a 3/16 inch Allen wrench.

    Insert a 1/8 inch Allen wrench (must be at least 4 inches long) and loosen retaining bolt.

    At muzzle end, remove both rib adjustment retaining machine screws.

    Turn rib adjustment thumb wheel (clockwise when viewed from above) until
    thumb wheel disengages from stud.

    Lift rib up out of retaining collar (muzzle end) and move entire rib forward. It will
    lift out of the slot cut into the false barrel. Be careful not to loose the round trunion
    nut on the receiver end of the rib.

    It only takes 5 minutes to change ribs.

    Good luck.

    If changing from the standard TA rib to the high TA rib, no ramp change is necessary.

    If changing to a low rib configuration, you will have to change the ramp.
    This is a little more involved.

    Remove the false barrel plug. Remove the angled cap screw that is threaded
    into the ramp from the barrel plug hole.

    Remove the 3/8 inch pipe plug inside the upper false barrel. The barrel can now be
    removed from the mono block. The new ramp is inserted to the slot.
