Steps 6 through 8
Step 6
 
Once again you will need your hammer and punch pin set because we are going to reinstall the extractor.

Take your extractor and slide the little extractor spring over the “spring arm” of the extractor (sorry not pictured).

Try to hold the extractor and spring together and place them both back into the extractor recess of the bolt (sorry not pictured).

Apply thumb pressure to line up the retainer hole of the extractor, marked in green, so the roll pin, marked in purple, can be reinserted.

Gently tap the roll pin into the retainer hole until it is flush with the bolt. No part of the roll pin should be protruding from any side.

Step 7
 
Now lets install the recoil rod back into the bolt. Take your recoil plate and a buffer, marked in yellow, and line the holes on them up.

Slide the recoil plate followed by a buffer on to the recoil rod, marked in green, from the front (the end that has the hole for the roll pin on the recoil rod). The recoil rod has one end flattened out so it is impossible to install the recoil plate from the other direction. Since the recoil rod is larger then the ejector rod it is also impossible to stick it through the wrong hole.

The buffer should be installed so that it separates the bolt from the recoil plate.


 
Now slide the recoil spring, marked in purple, onto the recoil rod, marked in green.
If you did this correctly the recoil assembly should look some thing like this, minus all the colors of course.
Take the recoil assembly, marked in purple, and slide it inside the bolt, marked in green, through the recoil rod hole.
As you compress the recoil assembly and bolt together, reinsert the roll pin, marked in green, through the front of the recoil rod. The roll pin should protrude equally on both sides. Once the roll pin is in place it is safe to decompress the recoil assembly.

Step 8
 
Next we are going to reinstall the firing pin. To do this, turn the bolt upside down and drop the firing pin, marked in green, into the firing pin recesses, colored purple, on the bolt. Make sure the firing pin is inserted in the same orientation as shown in the picture.


Now take the retention pin, colored in green, and insert it into the retention cut out hole. The retention pin should sit flush with the bolt. If it does not, then the firing pin may have to be moved a little to get the retention pin hole lined up on the inside.
