ok so here is my issue.
after installing my new upper on my lower, i run a function check. (safties, trigger charging handle) the function check sometimes fails. the trigger won't drop. if i break the weapon open, i can see the hammer is locked back just a little too far. if i press lightly on the back of the disconnector the hammer pops up a little and then it will fire. any thoughts? 
Thanks in advance MC |
| I have also encountered burs on the disconnector and or the hammer and have had to polish them off in order for the disconector to let go and let the trigger grab the hammer.... Also crap where the trigger and the hammer meet infront of the trigger will cause this but normally you can check your disconector by pressing down on the dissconector from the top and see if it releases the hammer then.... |

Ok so an update... After a liberal cleaning of all the parts, I seem to have made the issue better. Now it will fire when I snap the charging handle back from a full stroke. Apparently I wasn't pulling the CH back and letting it go "hard" enough. Just as a side note, I have tested this using the bolt hold catch and it seems that it won't release the hammer when I drop the bolt on a empty chamber from a caught open bolt. I am curious to see what the weapon will do when I take it to the range for the first time. Kinda nervous. I will let you guys know after a range trip.
Thanks MC |

Got it Fixed!
The problem was that the disconnector "tooth" (not sure what to call it) what just a touch too long. I filed that area down tested and everything works beautifully. Now I just need to run some ammo through it at the range. Hoping to get out this weekend. Thanks MC |

I personally would not shoot that gun at a public range. You have modified the disconnecter. If you fire that weapon and it doubles you could be in big trouble. The B.A.T.F. doesn't care why you modified it. If the modification results in a double, and your weapon is inspected, there is a chance you will be going to jail. Because you have created a machine gun with your modification. Your intend is not relevant. Tread carefully this is very slippery ground.

You are probably right. The odds of an A.T.F agent being at your local gun range are slim. However, the odds of a police officer being at your local gun range are pretty good. Get the one with an attitude or who happens to be having a bad day and things could get ugly. Just not worth the risk. Were talking about a $6 part and 10 minutes of time to replace it. Replace the disconnecter and be done with it.

Ok, first off I completely understand where EW1066's point is coming from. I did modify the disconnector. If you were to measure the disconnector now from when I started there is maybe .002" taken off. I understand what that portion of the Fire control group does. I did manually cycle the FCG with the trigger held in and the disconnector still grabs the hammer when the trigger is held back, when releasing the trigger it pops up to the cocked position, just as Mr. Stoner intended. I ALSO understand that manually cycling the FCG as a test is onliy one step in a proper test of the weapon and its components. The stresses of live fire and ammunition are different and crazy things happen. This has now gone from R&D to QA to Production for you IT/IS people out there. I am not going to believe that the modification has worked untill I THOROUGHLY test the weapon, just as I would not put a new server in place without testing it just as extensively. I have a very simple plan...
ONLY LOAD 2-3 Rounds per magazine. That way I can only have a double or triple and not a 30 round mag dump. I plan on this for at least the first hundred rounds. I do appreciate the advice... NOT the fear-mongering about the Leviathan on The Potomac. Please lets all put the tin foil away and cease with the haberdashery. Thanks Guys. MC |

Thank you for understanding that I was not trying to take a shot at you(no pun intended). I just would not want to see someone get in trouble for trying to fix something that the MFGR. should have caught in qc. Who made the lower parts kit that is in your gun? Have you considered calling them and telling them the problem? They may send you a new disconnecter, but you have to ask. You have a well thought out and viable plan to test the gun and I commend you for having the patience to do that for 100 rounds. I'm not that patient. I would rather just slap a new disconnecter in it and then shoot it till it bleeds.  .
Good luck and keep us posted EDUB |

The lpk is made by Timberwolf Tactical. It is one of their stainless steel kits. the only things in the kit that are stainless is the hammer and the trigger. I have tried to contact them and their website expired 3/8/2011 and is up for renewal or deletion.
No go there. I may have to just get a spare lpk before I go to the range that way I can swap them out and be gtg. Thanks Guys MC |

Thanks Guys MC Even when there is no doubt about a rifle I bring a spare LPK, bolt and when possible an entire rifle. Not that the paper target will gore me, it is just annoying to drive an hour to the range, pay, wait for a cease fire, set up target stands and have an equipment failure with no recourse other than going home for parts. |
