Installation:
Installation of the frame is easy to do. Most parts are the same as the stock frames.
1. Remove the trigger from your stock frame by pushing out the roll pin holding it in (you may need to unscrew the firing point set screw to get it out). If you are using a stock Nerve frame, be sure to also remove the trigger rest plate from the top. Reinstall the trigger in the USF frame.
2. Remove the powerswitch actuator from the stock frame by pushing out the roll pin holding it in. Reinstall the powerswitch actuator inside the USF frame.
3. Remove the lower board from the stock frame by pushing out the roll pins holding it in place, then reinstall in the USF.
4. Before you reinstall the frame onto the marker, adjust the trigger to your liking using the "adjusting" section below. You won't re-use the magnet in the stock frame.

Adjustments:
The trigger's firing point and post-travel adjustments are the same. However the pre-travel and magnetic return are different.
· Pre-travel adjustment: The magnet screw in the top of the frame is used to adjust the trigger pull's pre-travel length. Adjust it using a 5/32" allen wrench until you find a suitable pull.

· Magnetic return: The magnet inside the frame attracts the trigger's stock pre-travel set screw to reset the trigger. To adjust the strength of the magnet return, adjust the trigger's pre-travel screw to your liking. The closer it is to the magnet, the heavier the pull will be (and vice-versa).
