So I built my first thing, went and shot it, and everything worked. Then I noticed that I had my castle nut on the wrong way, and I couldn't tighten it down with my stock wrench.
So today I went and took it apart, and then I separated the upper from the lower, the buffer was up near the hammer and it looked like the spring was malformed, and the retainer fell out of the buffer tube when I took the buffer and spring out. So now I'm sitting here with the buffer tube and everything in place, but I can't get the buffer retainer to stay under the lip of the buffer tube, it just keeps popping out. The lip where the pin is held down, looks somewhat scuffed, and I'm wondering if there is much I can do with limited funds, tools, and knowledge about the system. Thank you, your help is very much appreciated. |

Here's the best I could get, I had to use a cell because our cameras are currently out of commission, so I apologize in advance.

Am I good to go or should I replace the pieces that got bent? |

It looks like you didn't have the receiver extension threaded in far enough and those scuff marks are from the buffer retainer moving around with the action.
I would simply loosen the castle nut, reinstall the retainer spring and retainer, and screw the receiver extension in a little more until it holds the retainer down. |

If the retainer still drops into the hole and it holds the buffer in place, I see no need to replace anything. Thank you for your help. Everything feels a lot more solid now. I actually had an issue at the range with the buffer coming out into the trigger group area, but I sort of just pushed it back and put the upper down really fast. I guess I didn't really want to over screw the thing and break it on my first build, so when I tried to do that extra turn the first time it was resistant, so I just backed off a little bit and I guess it wasn't enough. Again, thank you. This site has really been a life saver. I'll make sure I put some pictures up once we have a functioning camera, and once I get a rear sight for this. |
