How to install the sear spring in the APS-1 Grand Master series

1. Install the sear spring from the right side. With the orientation shown in the photo, insert the sear spring into the "easy housing pin" and then insert it into sear A. 


2. After inserting the "easy housing pin", use tweezers to hook the tip of the spring onto the protrusion of the frame, then gently push the pin all the way in. The right side is now complete.
Since the sear spring is fixed by the protrusion of the "easy housing pin", you can proceed with the subsequent work with peace of mind.


3. Insert the golden "sear A pin" into sear A from the left side.
Since the "sear A pin" has no resistance, it will not fall out if you press it from the opposite side with your finger.


4. Insert the sear spring in the direction shown in the photo, and hook it behind the "sear A pin" with tweezers.
Finally, confirm that the sear spring is in the groove of the "sear A pin". (Both left and right)


This completes the installation of the sear spring.
The right sear spring will no longer fly off due to the protrusion of the "easy housing pin", allowing you to work with peace of mind when installing the left sear spring or during subsequent assembly.
