I ordered a lower parts kit from so & so.com, needless to say the disconnector wouldnt fit in the groove on the trigger, after several failed attempts to mount it i decided to take the trusty ol dremel to it.
I got it to fit, then called so &so.com, and they sent me a replacment disconnector. Decided to change it out and its the same issue. So now I have to believe the groove in the trigger is to shallow. My question is, Is it safe to use this now that i have modified it? Is it legal, or did I inadvertantly do something illegal? http://i188.photobucket.com/albums/z306/fossil072301/photo2.jpg Here is a pic of the shaved disconnector on top of an unshaved one http://i188.photobucket.com/albums/z306/fossil072301/photo2-1.jpg http://i188.photobucket.com/albums/z306/fossil072301/photo1-1.jpg and a pic of the unshaved one in the trigger groove http://i188.photobucket.com/albums/z306/fossil072301/photo4.jpg |

Either the trigger or the disconnectors were improperly manufactured or finished.
Personally, I don't have a problem doing a little hand fitting to get a perfect fit. Disconnectors are stamped out, and if they are not properly cut out, it's possible that some flash material is present. Filing to remove the excess material (which should have been removed as part of the manufacturing process is not a problem. I'd guess that is the problem before suspecting that the trigger has a problem. Any chance of borrowing a disconnector and a trigger from a friend to confirm which part is actually bad? There's a chance that since you got the 2nd disconnector from the same source as the first that both came from a defective lot. If it's not the disconnector, then it has to be the trigger. If the problem is with the width of the channel in the trigger, I would replace the trigger, because widening the channel in the trigger would be more effort than simply replacing it (although I wouldn't have a problem widening the channel myself if there wasn't a easier alternative). Shaving a little from the sides of the disconnector to fit it to the channel in the trigger is not unsafe or illegal. It's not like you're altering the disconnector engagement with the hammer. Nor will it affect trigger function (as long as the disconnector is not a high friction fit). When you're done shaving it, it should slide smoothly in the trigger channel, without friction, and without excessive slop. |

IF (big if) modifying your parts results in the gun going full auto then it can land you in big trouble. just shaping grinding parts to fit without inducing full auto capability would be perfectly ok.
getting mass produced parts from multiple makers and putting them together into a rifle it is actually rather amazing we have relatively few parts fit issues in the AR world. And if they occur I don't have a problem with a little hand fitting either |
