[ARCHIVED THREAD] - AR57 Lower - Out of Spec (Page 1 of 2)
Posted: 12/15/2012 12:53:41 PM EDT
| There was a thread in the AR Discussion section but it's magically disappeared. I received three of the AR57 lowers yesterday, all of them are out of spec for the takedown/pivot holes. On all three I can get the pivot pin in but not the takedown, and even getting the pivot pin to line up causes the a large gap between the upper/lower. I can only speak for the three that I have, but I know before the other thread went to who knows where that others were stating the same thing. I'm looking for advice on what to do? Any input welcomed. |

Any input welcomed. There's a whole bunch of threads right now regarding this. Here are 4 of them - http://www.ar15.com/forums/t_3_4/594209_AIM_Surplus_AR_FIFTEEN___aka_AR_57__out_of_spec_issues_.html I gotta say I'm concerned as I ordered 3 of them yesterday. Although my concern is mitigated because it's AIM and they will take care of any issues regardless. Is it possible to have AIM QC my order before sending it out and see if it mates up to an on hand upper? I'd rather not have to take an upper to the FFL where I'll be picking them up, and to that end I don't even have any pivot or takedown pins on hand. I'd hate to have to buy some, and then in a week or two have to send them back after I've already payed the transfer fee. Thanks guys. I can send my order number if you could check my lowers out before sending them. |

I ordered 3 too. THANK YOU for checking hundreds of lowers to ensure great service. I ordered mine Friday night and got the email today they are shipping tomorrow. It's great to see AIM knows what service is and doesn't make excuses during the busy periods.

i just went through our stock, of the 700 we have here, 70 were out of spec the other 630 are going to ship If no one has said it yet today, let me be the first to say "You guys rock!" Then again, if my order was part of the 70 that don't ship I take it all back.

| Just got 3 in. Serial number range in the 1480s-1490s. All 3 out of spec. One was in between the other 2 and was so out of spec., that you could not close it, the other 2 were could close, but you had to use a plastic mallet to push in the take down pin. Once put together, you could see that the gap between the upper and lower was greater at the back of the receiver, with almost no gap at the front of the receiver (looking from the side). They were test fitted to a new colt 6920 upper and a new PSA midlength (same results from both). I just called 5 minutes ago and spoke to a young lady who said she would pass the information to Dennis and he would call me. They are good looking receivers, only wish they would fit. |
| Pick mine up tomorrow. Not sure how to check for fit as I want to build it as a pistol lower and I only have rifle uppers for now. I haven't gotten all my parts (upper receiver) for the pistol upper. Would I be breaking any laws if I check it on one of my rifle uppers. (unassembled lower) |
| I talked with Dennis, only issue I'm having now is I'm being told I'll have to pay $45 in transfer fees again, Dennis said it will have to ship to an FFL and the place I'm going through is saying if they are new serial numbers that I'll have to pay again. Any suggestions on what to do here? |

Have you explained to the your Transfer Dealer that this is for replacements on a defective product? I would be shocked if they do not understand. If they are not willing to work with you, let me know ([email protected]). Especially if they are on our Dealer Network. Thanks, and I really appreciate your patience. Erik

Erik Please get more stuff in stock so I can order from you, you guys are one of the best in the business. |

Erik Thanks for the great customer service, they are in your dealer network. When I called and explained why I needed to have their FFL faxed, I mentioned that I was told by Dennis that due to the fact this were replacements that he didn't think they'd have to have the transfer fee (Dennis had mentioned this because I brought up to him about if I'd have to pay the transfer fee), they told me that if it had a different serial number that I'd have to pay transfer fees. I'll keep you posted with what happens. |

| So I told two friends about these lowers that are both pretty new to ARs and they both came over last nigh to put them together. Oh boy it was interesting to as the least. I was able to get the upper and lower on two to line up no problem with uppers (didn't their other two as they only had one LPK each) but assembling the lowers was rediculous. The safety selector hole is just barely too low making it impossible to install the selector, the tigger pin holes on one were crazy tight and the other were pushed in with my fingers. Both of these issues weren't that bad just really annoying but then when I tried to put a pistol grip on them the gap between the receiver and the grip ( I tried several different ones and they all liked the same) looked really bad so I "shaped" the grip to fit. Okay so another inconvienve but whatever all the while I'm telling both of them "it's not usually this difficult". "Aim Surplus is a great company to deal with, we could always wait until tomorrow and see what the say but both of them wanted to me to keep going so then came the buffer tube, talk about tight. I'ved had some buffer tubes that needed to have the threads worked a bit ( screw it in a little then back it off repeat until properly timed) but this thing after about two full rotations wasn't going anymore. One guy opted to wait the other decided he would get it in and although it worked I don't know that I would ever suggest doing this. He used a six foot level as a torque bar and got it done. The other guy seeing that this worked did the same. So any way now they have complete lowers but I'm wondering if it would be worth calling Dennis abou the other two because in a couple weeks I'm going to be building the other two for them once they get their parts kits. |

thanks erik for getting us all fixed up.
i've got two defectives. trigger pins are looser than i think they should be and buffer tube won't come close to going in. not to mention i had to clearance the lower by a thousandth or so to get the selector in the hole. i'll get up with dennis tomorrow. thanks again guys, great business! |
| I have three and none of them will fit on an upper without hitting the pins in with a hammer (no I didn't try it but I think I could get at least one of them in with a hammer). I'll call Dennis tomorrow. I am really disappointed that people are finding other fit issues as well. It seems likely the whole receiver is out of spec. |

I just finished putting my AR57 lower together. My AR57 UPPER didn't fit very well, the takedown and pivot pins wouldn't line up. I compared to a M&P lower and a POF lower that the upper fit just fine. It seems the radius on the curve in front of the tube threads on the left side wasn't cut right. 2 minutes with the dremel and a sharpie and the upper could slide back just far enough for the pin holes to line up.
It all fits up fine now. Sometimes you have to make adjustments. Its a $74 lower not $299 POF P-415 lower :-) Not the first time I've had to make adjustments on AR parts, won't be the last time. Don't send it back, make it work. I was more unhappy with the lack of crispness of the markings. My color fill on the safe and fire pictos looks a little crappy. |

Got my 3 today and 2 way out of spec and 1 that you could probably like and hammer on to get it to fit. so far left 2 mesages and no calls from 57. I get the impression that this is a big problem compounded by the rush.
Each of mine have multiple problems. Inside of 2 of them have the fire control area milled way off to one side. 2 of them have the grip screw hole too far forward. And all 3 you can't get an upper on without a mallet to hammer the pins in. They are so off center the bolt binds in the stock tube when you charge it. All this before even attempting to put a trigger or mag I them. With them milled off center I have to believe feeding problems are enevitable. Again I hope 5.7 makes it right. bottom is milled in the center. you can see the other 2 are off set and there is an overcut in the front of the mag well on the other 2 
You can see how far offset the upper is on the left side there

Got my replacements Today Good news is they all pin to uppers. The Bad is the Grip Screw hole is about 1/8" back to far back, thus making the detent spring not line up. I know I can just ream the grip a little but shouldnt have to. Oh well  May I ask when you got a hold of Dennis initially? I was able to talk to him on Monday, but haven't been able to reach him since. I don't trust the FFL I went through very much and am trying to get an idea of when I should start hounding them to see if they came in. The FFL I'm using seemed extremely bothered by the fact that I was asking for them send the FFL to the manufacturer. |

Dennis said he sent out a ton of replacements Thrusday, I'm one of the first to get the replacements because it's only takes one day ship time to my location. He also said there where only like two FFL's he was waiting for.
Hint-When you call make sure to use option 2 for Tech support. |

My buddy and I just assembled two AR57 lowers he recently purchased from AIM. We did find a few minor issues, but nothing insurmountable.
The buffer retainer pin hole was a little too tight, and needed to be reamed out a little with a 1/4" drill bit. The grip mounting hole was off a little, so we had to enlarge the hole in the grip to allow clearance for the grip mounting screw, and the magazine release button was a little tight on one of them. We swapped the magazine release button with one from another LPK, and it fit fine, so that was probably just a "stacking" of tolerances of both parts. We tried four different uppers. We fitted a Colt, a Stag, a BCM, and a Spikes upper. All fit fine, with minimal slop and no excessive or insufficient clearances all around. All in all, I am pretty impressed with the two AR57 lowers I have personal experience with, especially after reading about the problems other people were encountering. The only issues we found were minor, and fairly easy to overcome. Here are some pictures of one of the completed AR57 lowers: http://ImageEvent.com/ken6ppc/arfifteencompletelower |
My 2 are both out of spec. I have a low 700 serial # and a low 800. The 800 is much worse. I'll give them a call Monday. I'm sure glad I saw the other thread on this, as these were just going to be sitting in the safe for a while.I'm not happy to hear that I will have to pay FFL fees again.

| I want to thank AIM Surplus for all their help, although they didn't make the product I'm sure it's been a headache for them. I managed to get my replacement today, there was still cussing involved but is together. The mag catch is angled too far inward making it so the mags need alil more force to get in but I'm not sure if that's the lower. I to had to enlarge the hole on my grip to get the holes to line up (thank goodness for ARFCOM, I was having a brain fart and was considering altering the lower... much easier to alter the grip). Managed to break a selector because I couldn't get it to go through, the trigger assembly didn't sit low enough in the lower cause the selector to hit, but the breakage was more me being pissed and not taking my time. |

Guys make sure you explain to your FFL Transfer that these are replacements for lowers that had to be returned. I would be shocked if they are going to charge you again. I have yet to have a dealer demand a fee when you explain the issue. And if they are on our Dealer Transfer Network let me know immediately. I will get it straightened out.
