  • The fit between the pivot pin and new trigger is very tight.
    It might be necessary to file the pivot pin to fit.
    I have colored the pivot pin with magic marker, so that I could see any high spots after trying it in the trigger.

  • Assemble the four parts to verify fit before installing into frame.
    The top set screw will be used to secure the trigger pin.
    You will not have adjustment for take-up, but you will find very little anyway.

  • Assemble the trigger parts in the frame.
    Make sure that the spring tail is at 5:00 and that you press in on the spring as you insert the pin.
    The groove in the pin goes to the top.

  • If you have failure to fire because of a lack of over-travel: you will need to file the area in the green, on the plastic stock.
    File it square so that the trigger can move further back. This is best done with the frame out of the stock.
