I recently purchase a NFA billet upper and lower assembly and I am having an issue. The rear take down pin is very tight when I place the upper on it. I also had the bolt sticking in the buffer tube when I charged it to the rear.
I noticed that I had bent the tip of my buffer retainer pin. So I took my buffer tube off and placed the upper receiver back on. It appears that the upper does not line up with lower properly. If anyone has any ideas let me know.

I'm not sure I'm fully smelling what you're stepping in...
The pin being tight should loosen up over time. You might even have to push it out with something other than your finger at first. I've never seen this as a sign of a deeper problem though I guess it could since you're having another problem. It's that second problem I don't fully follow. Can you show he bent piece in a photo? Did the rifle charge properly, or was it during the first attempt to charge that you bent the retainer? Is the last picture the attempt to show the supposed misalignment? If so are you just holding them together is is the rear TD pin in place? |

If so are you just holding them together is is the rear TD pin in place? I guess that I should have explained it better. When both pins are installed fully the upper is not perfectly aligned with the lower. That is evident by the photos I posted above however I can post them again with the pins in. I went and grabbed a standard flat top upper and tried it on this lower and my issues are solved. So I will be contacting who I bought the upper from to see if I can exchange it. Here are a few photos with the LRBHO upper installed vs a standard flat top upper installed. Here is the LRBHO upper installed:

Sorry to hear about this problem Well I do not seem to have any issue with the lower. If I do not get my replacement upper in time I will go ahead and build it with a standard flat top upper. That way I can at least start shooting it this weekend and if all goes well send in my $200 to have it SBR'd. |

So yeah, that was my thread. After I got mine and was having the same problems as the op, I started researching and looked like there were multiple other reports of similar issues with NFA uppers, so when I returned mine, I just ordered the side charger, and Im glad I did. It is different than what I am use to, but the fact that the back end, where the charging handle normally is, is closed off, makes it nice with a suppressor because no gas in my eye. pic for reference: http://i158.photobucket.com/albums/t120/adam_perdue/20160304_211340_zps2w7gnhsl.jpg Quote HistoryQuoted:

However depending on how they handle my return of the upper I can use that handle on a different AR. |

The replacements better be ready on time. I hate waiting on something that should have worked the first time. |

I know they retail for $100 more on the NFA web site, but did they cut you a break for the problem you had with the other upper? As much as I prefer a traditional-style upper due to familiarity, if the upcharge isn't too bad, I think I'd rather use what appears to be a more consistently higher quality upper than one which has recently been plagued with issues. And, they have side-chargers in stock, rather than having to wait another month or more. |

Sorry to see this - looks like more than a few of these are screwed up. Wish I could say I'm surprised, but based on my experience I'm not:
http://www.ar15.com/forums/t_3_15/689817_NFA_LRBHO_Upper___Not_Happy___What_s_your_experience_.html They appear to have some major QC issues and until they get it sorted, I'm done with NFA. I went with a couple cheap slick side Anderson uppers temporarily and everything went right together as it should - unfortunately it looks like a pass on LRBHO for now. Good luck getting it resolved - I personally wouldn't wait on a replacement from NFA, at least not until they get their QC under control. |

I have an NFA upper and lower set. My rear pin is tight. I suspect it will loosen up after time.
When I completed the build, the buffer would stick when I pulled it back. After less than 10 rounds the problem fixed itself. It stuck back on the first few shots. Then it stopped. And fired flawlessly. However, when I pulled the bold back by hand, I could still get it to stick. After 150 rounds that stopped. I can no longer get the bolt to stick back no matter how far I pull it back. |

Well I went and exchanged the slick side upper for the NFA side charging upper and it has none of the issues that the slick side had. So this afternoon I should have it together and will post a picture.

I fired 350 rounds yesterday and it ran flawlessly except when I tried some specialty subsonic rounds. I had some HPR subsonic 147grn ammo that would not cycle the bolt. However I tried 8 other kinds of ammo and they all worked perfectly. I am going to shoot it some after church today as well.

Did anyone opt to get a new upper and not gotten it yet?
I was told replacements were going to be sent out early April. That changed to mid-April. Which changed to late-April. It's now late April and I've been stuck 2 months with a non-working upper. Did any of you opt to wait? Or did everyone go for a side charger? |
