| I have a dpms stainless trigger grioup in a new gun. the disconnectr is latching in the top of the hammer instead of down by the pivot anyideas of why or solutions would be helpful |

Welcome to ARFCOM!
I'm not clear on what the problem is. Can you explain further what you mean by the disconnector "latching" on the hammer? Does the disconnector move freely in the trigger? Is the spring for the disconnector installed correctly? Is the trigger pin smooth and installed properly? Also, pictures are very helpful in explaining this sort of problem, so if you can post some, that would speed things up. |

Two things
1. Stainless trigger groups never work well in the long run. While ss alloys exist that would work, they would cost crazy amounts of money. Yours will fail given time. They gall, bind, and become unsafe. 2. The disconnector latches the hammer at the hook that is under the head of the hammer, not at the sear points. That's where the trigger its self engages the hammer. The disconnecor keeps the hammer from following after the weapon cycles while the trigger is depressed. Once you take your finger off the trigger, the disconnector will disengage, and the hammer will click to catching the sear. If when the disconnector disengages, the hammer "fires" your trigger is missing one of its sear points. You need to look up "ar15 function test" and tell us where it fails. From the little info your post has. It sounds like it works fine, and that you don't understand how it's supposed to work and are assuming something is wrong. Sorry. |
| So when I cock the hammer back the disconnected catches right under the hammer face. I squeeze the trigger and the disconnected does not release instead it travels farther forward on the hammer. have built 11 of these guns but never with as trigger group. I currently have three of these and all three are exactly the same. will try to post pics tomorrow . thanks for all your help |

If it stops on the disconnector, then the disconnector is NOT installed correctly, probably with the spring in wrong - or with the wrong spring. The disconnector should be way too low with the trigger forward for it to touch the hammer at all. With the trigger held back, the hammer's rear hook should catch on the disconnector and stay there until the trigger goes forward, when the hammer should transfer from the disconnector to the trigger. If this does not happen, there is either something wrong with your parts, or the way they are installed. |
