Disassembly of Trigger and Bolt stop

1. Field Strip the gun. (Instructions)

2. Remove Trigger Shield (if you made one)

3. Locate the Trigger Pivot Retainer (looks like a bent paper clip that the red arrow is pointing to in Fig. 1)

4. Using the back of 2 small drill bits, press down on the Trigger Pivot retainer as close to the trigger as you can and while holding the retainer down, push out the Trigger Pivot pin (Fig. 2)

5. Rotate the trigger and disconnector assembly out of the trigger guard.  You may have to wiggle the disconnector assembly to get it to release from the sear. (Fig. 3)

6. The trigger will now slip off the end of the disconnector assembly and the trigger spring and plunger will probably fall out so don't loose them.  

7. Rotate the bolt stop assembly to where the hole of the trigger pin is sticking out of the hole to the trigger guard (Fig. 4 red circle).  With a little wiggling the assembly will come out.  Be careful not to let the small plunger and spring to fall out of the side of the bolt stop button, it is small and hard to find on the floor.

Assembly of Trigger and Bolt stop

1. Insert the Bolt stop assembly by lining up the finger button with the hole, have the other end sticking out of the trigger guard. (Fig. 4)

2. Rotate the bolt stop assembly clockwise and let the end of the assembly rest inside the grip, there is a small groove it sits in.

3. Insert the spring and plunger into the vertical hole on top of the trigger.

4. Insert the round end of the of the disconnector assembly into the top horizontal hole on the trigger and rotate the trigger so the plunger is being held in by the bar sticking out of the disconnector assembly. (Fig. 5 red circle)

5. Rotate the trigger and disconnector assembly counter clockwise and into the trigger guard. (Fig. 5 red arrow) If the bolt stop is not resting in the grip or is still sticking out of the guard, the trigger will not go in all the way.

6. Insert trigger pin.  The notch in the pin should be on the opposite side of the bolt stop assembly.  (Fig. 6 red arrow) Some wiggling of the trigger is usually needed to get the pin properly aligned.

7. The pin will go most of the way in except a little bit (Fig. 7 red circle).  You need to push down on the Trigger Pivot retainer, like you did in the disassembly step 4, and push the pin until it is flush with the frame.

8.  Using the back of a small drill bit (without holding down the trigger pivot retainer) push the pin farther into the grip until a "click" is heard.  This means the pin is locked in by the retainer and should not vibrate out.
