The buffer pad is the T shaped block that sits in the back of the receiver. Its there to cushion the bolt when it fires a fairly hot load. The bolt comes back a little harder then normal and the 2 wings on the back of the bolt bounce off that "pad" in this gun its just a plastic T shape block. Other guns its rubber, or even a plastic disk with a spring behind it. I think some real type ARs have the disk and spring behind the bolt.
Anyway, dont forget to put this in correctly, if its not in right it may cause issues with the bolt not comming back fully and stove piping the spent shell.
Ive marked the images in red where the bolt makes contact on the buffer pad to help you figure out how it sits in the receiver. Yours may have dents in it already mine does. The bolt has hit hard enough to mark it a little. The yellow T is the top that the top part of the block that sits ontop the trigger housing.
Also in the second image i have pictures of the guide rod. This rides inside the bolt spring and it guides the back of the bolt so that it moves back and forth in the receiver square and doesnt bind or rub on the walls of the receiver. The front of the bolt rides in the black plate that also helps kick the spent shell out. The plate guides the front, the guide rod guides the back of the bolt.
The head of the guide rod goes into the hole on the inside of the receiver.
If you search my name, search past posts or all my posts for other images of the inside if you need more detailed images on how the receiver parts fit into the receiver.
When i put the bolt back in i put the head of the guide rod into the hole first, i let the spring bend a little. Then i push the spring into the bolt and slowly drop the back of the bolt in as im compressing the spring around the guide rod. As its compressing i lower in the front till the breech face goes down into the receiver. Just before the bolt is all the way down into the receiver i put the charge handle in on the extractor side and then drop the bolt all the way down in ontop the charge handel.
Then you have to pull the charge hande all the way back as you insert the trigger housing.
