So my buffer retainer pin and spring aren't really settling down too much, and further, everytime I separate my upper from my lower, the spring and pin are stuck somewhere inside my trigger/selector area and my recoil-spring is pushing my recoil buffer into my hammer.
What should I do? I haven't shot the thing yet, but I'm hesitant to now that I've dry-cycled my gun a few times and keep having this issue. |

Pretty sure I'm good without the tutorials. Here's what's going on with it: How far I have it threaded into the lower: http://s8.postimg.org/s8dva130l/IMAG0211.jpg With everything installed: http://s27.postimg.org/fb67jbv0z/IMAG0213.jpg Try again. Push the pin down and rotate the extension another turn so its sitting on top of the shoulder of the pin, thus holding it down. Take the advice and watch a YouTube video. |

The only thing worse than ignorance is arrogance.
Your receiver extension needs about 2 more full rotations. You asked your question now shut up and listen. Go watch the YouTube video. ETA: upon closer inspection of your photos it appears that your receiver extension is missing the lip on the bottom. Without that lip, you'll need to thread the RE too far to capture the buffer retainer and it will bind with the upper. |

| Woah, simmer down y'all. First build, pretty decent at reading directions. I guess I need to turn it a few more revolutions. Problem is, I tried this before and didn't have space to fit the the whole retainer etc. in. I guess it does matter where you start screwing the tube in on the thread of the lower? Gonna be a pain in the ass to reassemble, I'll just do it later I guess. Read that it was okay to run without it? |

Compress it while threading the RE into place. It should cover the edge of the retainer, thread it until it the retainer is securely held in place OR the retainer binds (in which case back it off a turn). Just go watch the video. Stop pretending that you know what you're doing. |

It isn't going to work like that. Without the buffer tube holding the retainer in place it will fly out and jam the action with every shot. The bolt will also travel too far back and the spent brass can fly back into the action. The Bolt face should stay 1/8-1/4" inside the ejection port when the charging handle is pull all the way back. Push the retainer down and screw the tube in until it just about hits the center protrusion of the retainer. |

Okay! I know what to do seeing some of the reference photos. Gonna take the thing to the bench when I get the chance, and if I can't get it to work perfectly, I'll take the dremel to the buffer tube to cut out a slot. Thanks for the help y'all. STOP DICKING AROUND. You've been given advice, utilize it! IMO shit can the retaining pin & spring. You don't need it. Or do some WECSOG on the tube, as you already have your mind set on. |

Lol, you remind me of me when I was 15.
I don't need your advice, I know what I'm doing. Post pic- buffer tube is at least 720 degrees too far outward. 
I'm just giving you shit, but you need to stick the spring and buffer retainer in their hole, THEN (while keeping retainer depressed downward) spin the tube further inward, until it overlaps the buffer retainer. The buffer does not hold the retainer in, the buffer tube does. |

Noooo..  .Either you turn the tube in until it retains the pin, or just leave the pin/spring out if you don't want to do it right. The carbine will function without it but a PITA when you want to get the BCG out.

Don't Dremel the damn thing. Just install it correctly. |

I would not make a cut like that in the buffer tube, or else the screwed in buffer tube could extend beyond the receiver and make it impossible to close the upper down on the lower. Like other have said: Put buffer spring in hole Put buffer detent in hole Press detent down with finger and screw in buffer tube until the edge of the buffer tube rests on the shoulder of the detent. Install buffer spring Install buffer by carefully pressing in the buffer detent and inserting the buffer in the tube. When you are done the buffer will be held in the tube by the pin sticking up. |

My Spikes Receiver Extensions have the lips and my PSA Premium RE parts kits don't have the lips. Or maybe it's the other way around... Either way both work great but you have to get them screwed in enough inside the lower receiver to cover that buffer retaining pin shoulder. |

The videos I watched were not as clear as you guys have been on the buffer tube covering the retainer pin. If you all didn't know, I'm a college student in an apartment 3 hours from home, when I go back for break I'm going to make this all right. I don't have a vice where I'm at right now, and there's no way I can manipulate the parts where they are at right now.
Does it matter where you start on the thread of the lower? Is there an optimum angle to start at? I guess I'll figure it all out when I have time. Also, does it matter that I don't have the pin and spring in right now, when I'm running a carbine buffer/recoil-spring with a mid-length gas system on a 14.5" barrel? |

This thread is so full of fail.
1) keep your dremel FAR AWAY from your AR 2) why are people advocating half ass assembling the lower and throwing away the buffer retainer? 3) the answer was posted yesterday why is this still going on? OP if you lived in my area, I'd do it for you. Please go into the hometown forum, and post a "someone local please help" thread. You'd be surprised how many people on here would get you squared away and give your work a once over to make sure you don't have any other issues. |

The rifle will work fine without the buffer retainer pin, but the buffer will go shooting off every time you pop the rear pin and seperate the upper and lower. Again, the pin is NOT REQUIRED for proper operation, it just makes it easier on you when you field strip the rifle. |

You don't need a vice, just a castle nut wrench. Put the lower between your knees and torque the castle nut loose. Fix your issue, tighten the castle nut and get back to beer pong. Quoted:

BUT like a typical college trustifairian ignores the advice given. Fuk him let him figure it out on his/her own. To the OP. I don't give 2fuks what you do in real life. Throwing the "Im a a college student" makes you look that much more pathetic. |

Does it matter where you start on the thread of the lower? Is there an optimum angle to start at? I guess I'll figure it all out when I have time. A good trick is to turn the tube counterclockwise until you feel the threads click on the start ramp of the threading, then slowly engage the threads and turn it in clockwise if it doesn't line up, give it one more rotation. it should be smooth turning, without binding once you get the tube near the buffer detent hole drop in the spring and the detent hold it down and turn the buffer in, over running the detent some buffer tubes have a notch in alignment with the collapsable stock detents some have a lip that sticks out from the face some are cheap and have no extra features "when in doubt, modify the cheapest part" |
