the Build-It-Yourself forum in the AR15 section here has diagrams and videos for building, and in reverse, stripping your AR. Should be all the instructions you need to take it down to the bare parts.

detailed pictures of the internals could help. contact points. spring setups. hammer edges
but honestly you probably just could buy a new FCG and slap it in and it would be fine. 30ish bucks and your back up and running. |

Check the disconnector spring. The big side should go down into the trigger.
Make sure it moves free. |

You just posted that you have a full auto AR-15 on the internet. WOW. For $200- $300 you can have a new lower that won't get you thrown in jail. I know you said that you bought it from someone but I wouldn't risk it on the ATF being reasonable about this issue. Get rid of that lower now!!

The hammer and trigger springs look right.
Can't see any disconnector spring at all. not even a sliver of one. Does the disconnector in the center of the trigger move forward tward the magwell under spring pressure if you pull it back to the rear of the rifle with the hammer in the up position as shown in the pics? |

I could be mistaken, but it appears your disconnector spring may be missing.
ETA: Looking at the first picture, the circular cutout in the trigger should be housing a spring between the trigger and disconnector. If there is none, that is your problem. There does not appear to be one in the picture. |

I don't think you have a disconnector spring in there. Go and perform a functions check. It is a .60 cent piece or cheaper you can find at a gunshow. If not, buy a lower kit and have the extra springs that break and are lost when building. :)

Look around locally for someone who can walk you through the reassembly. It's fun to learn about the internals, and even better when someone is there to explain it.
- BG PS. I would have pissed myself if he posted pictures of an auto-sear installed and pranked all of us.  |

The disconnector spring is missing. If you look at pic's, you can see the two indicators. The first is that the disconnector is sitting level with the trigger well walls, and the second, you can not see the top of the Spring.
If you take the hammer and try to lock it with the trigger pulled back it should lock, if it dose not, it is more then likely an issue with the disconnector. BTW....I ran into a similar issue with the one AR I built. But my issue was with the DPMS trigger not being machined all the way. It had a lip at the bottom that caused the disconnector to get jammed into the well. I had to use a dremel with a cutter wheel to take it out. Which could be your issue if the spring is there. If you have a 1/8" punch, it's pretty easy to take a part and fix and just about any gun shop will have the parts that you will need if some thing is missing or out of spec. This is the link I used to to help me build both of my AR's: http://www.ar15.com/forums/topic.html?b=3&f=4&t=226782 |

thx for all the help. it is a missing spring. suffice it to say that this is the last time i buy a lower and put together a frankengun. i cant believe the problems that i am having.
1). the detent and spring were put in backwards on the bolt release lever. 2). the roll pin on the trigger guard was put on the wrong side. i had a hell of a time getting it out to install a winter trigger guard. 3). my current issue, missing spring. i appreciate all the help. im gonna have the entire lower redone with a stag lower parts kit. |

Word to the wise, when you are shooting a new automatic for the first time. Load one round and fire, then load two rounds. If it doubles on the second round, you are alerted you might have an issue.

I didn't realize that a missing disconnect spring will make the gun fire full auto so easily. Are you talking just a couple of bursts, or is it strait up full auto?

All depends on the bolt/hammer/ammo combo you have. But also it is not safe. Please don't think you can leave it out to have an illegal full auto rifle. The disconnector being loose and not working is very unsafe and the slam fire can make the round go off in partial out of battery and the rifle can blow up in your face. Don't try this at home on purpose. |

A quick, safe, easy way to fix this would be to pull out the all the FCG components, throw them away, and replace it all with new. I only mention this because there was a member of another forum who ended up doing a year in prison because his gun he bought used went FA and ended up having an M16 part in it. If there is no way to tell what the guy did or what parts he used in his build, or how to reach him, it is worth the $50 bucks or so just to get a new, safe, legal trigger group and have some degree of certainty what is in the gun. JMHO, but in this case it is a small price to pay to remove any and all doubt.
