Can an AR15 be damaged by doubling? I took my new build to the range over the weekend, and after 50 rounds it had double fired 4 times. I unloaded it, cased it up, and put it away. I have spoken to the manufacturer of the LPK and they intend to make good on replacement of any FCG parts necessary. My question is, should I be concerned about any possible damage to the upper or lower recievers from possible discharge while out of battery? Hope I explained that clearly. Thanks.

Is it possible to hold the gun wrong, causing it to double. Like an accidental bumpfire?
I know the M1/M14 will if you dont hold it right. If it happend 4/50... that is 8% I would re-install the FCG and try it again. If the mfg is replacing it just use the new parts and return the old. Maybe preform the semi-auto function test on it. w/o a magaizne or ammo in the chamber pull back c/h and let go. put on fire and drop the hammer. Keep pressure on the trigger and recharge the rifle. If the hammer follows home something is wrong. I doubt the double fire hurt it... Continuing the practice will though. Out of battery fire is not fun. |

The only damage that can occur from that would happen to your backside should the BATFE convict you of an possession or manufacture of an illegal machine gun. Disassemble that lower and throw the suspect parts away. Agreed. I couldn't believe what the guy from the LPK manufacturer said when I talked to him on the phone. I told him that my gun was double firing, one discharge on the pull, one on the release, his response... "That's not necessarily a bad thing". 
Wow! Couldn't believe my ears. I told him, "Yeah maybe for somebody, but I need one round fired for one pull and release of the trigger. The local ranges here are very strict about rapid fire and double taps. I can't have a gun that double fires". (not to mention the law!  )
Per their request, I'm sending them the FCG today. It is lousy that I'm going to have an un operational peice until they send me a replacement FCG. I figured they would just send me replacements, but I guess they want to see the FCG first. Probably to make sure I didn't screw up the FCG doing some kind of homemade trigger job. (which I didn't). I'm just kind of bummed that I had problems with brand new "quality" parts. I expected more, but atleast they are going to make good on it. |

Glad to hear they are fixing it. I think most of us have at least 5-6 unoperational guns in build at the same time. Some of mine are years old. I need to get my ADD in check and buy some lowers to put all the parts on

no worries of damage, its designed to do that, and detuned for us 
a few months ago someone posted the same thing, and someone said he had the bolt catch and disconector spring swapped, and it fixed it....sounds odd to me, that it MAY be possible to swap 2 springs and get it to fire more than one shot. Pull the parts, send them back ASAP I dont think you are getting this from holding it wrong

LOL! I know what you mean. This is what I do off of the walls

If the trigger pin walks out from right to left, you can get double fires. Found that out the hard way. |

Who the hell are we talking about here? Sounds like these clowns shouldn't be in the business. |

I'd rather not say, as I didn't start the thread with the intention to bash the company, nor do I hold the company responsible for the statements of one employee. Needless to say, I was surprised by his statement, to say the least, and dissapointed with the apparent lack of quality of the part/s in question. |

It's out of spec FCG parts. And NO. You can't damage the weapon that way. The AR is not capable of firing out of battery. I think ADCO posted a cut away of the BCG to illustrate that the bolt lugs are locked into the barrel extenstion before the firing pin can even touch the primer.

Almost all the double feed I have ever gotten were caused by the mag. Try using a different mag.
Double feeding will not cause damage. ETA: Misread. Thought OP was talking about double feeding. Have the MFG fix the problem. Doubling can put you in a bad situation. I've also seen Marines at the firing range doubling with their M16s. Nothing wrong with the FCG, they just were squeezing the trigger too long which cause it to bump fire. |

its not going to damage anything except the parts that are already damaged. i would guess theres either a problem with your disconnector, disconnector spring, or the hammer....and there isnt a good "grasp" from the disconnector to the hammer after the bolt cycles, causing the hammer to drop a second time possibly from recoil vibrations.
as far as "omg i have to get this disassembled now" i doubt the atf will be kicking your door down for having a broken rifle so long as you have obvious intent not to use it (in a safe unloaded). however you dont need to be taking this anywhere to fire, period. aside from the fact that its illegal to be using a weapon capable of shooting more than 1 shot per trigger pull, you have a gun with BROKEN or DEFECTIVE parts, its extremely unsafe to be using this weapon as you could have accidental/unintentional discharges (if its just the disconenctor, it shouldnt have an AD unless the trigger is held back, but still...unsafe until you can verify whats wrong). a new LPK and you should be back in business. |

Ok, so here is the update...
2 days after the mfg. recieved my defective FCG I decided to call and check status. I was told by a customer service rep that they hadn't gotten to my parts yet because "all of the guys are busy building rifles". So, I'm left to assume that building rifles for new/potential customers is more important, or takes absolute precidence over solving the issues of existing customers. If it was a normal return I would completely understand this. However, this is not a normal return, it is a defective exchange. I would think that some level of priority would be placed on correcting THEIR mistake. It only takes 2-3 minutes to diagnose a FCG. Really, all they have to do is send me a new trigger, hammer, and disconnector, then they can decide which part is actually out of spec on their own time. Doesn't take to long to drop 3 new parts in and envelope, print a label and send it on its way. So I called again today, because at this point I feel there is no reason why my parts shouldn't be on the way by the end of the day. I spoke with a CUSTOMER SERVICE REP who told me that he did not have access to my information, and could not tell me the status of my defective return. Isn't that what a customer service rep does? So, at this point, I am supposedly waitng for a call back from someone there who can actually help me. What a joke! Sorry for the long winded rant, but I had to vent. I want to ask these people how they would feel if I took their rifles away for 2 weeks because of something that wasn't their fault. Maybe I'm over reacting, but I feel like this is a bunch of b.s. Thanks for listening. Oh yeah, forgot to say that I had been holding off on dropping the name of this company but if they don't straighten this $#^% out soon, I 'm name droppin like a motha. |
| I realize that your question was about damage and agree with everyone about that being ok . I have to agree about the disconnector and spring though because every time I have seen this it is either a burr on the disconnector or spring not in all the way or upside down. I will wait to see what turns out to be the cause, it may have been an easy fix. |
| Yes, I understand the disconnector spring is a common problem. Before inquiring about replacement parts I dis-assembled the entire FCG and re assembled it. Disconnector spring inserted wide end first. Re checked FCG for function. Failed function check. I too am curious what the final conclusion will be (if they even tell me, I will probably have to call about that too). Just wish they would hurry up. |
