Installed a VQ trigger & sear in my 5.5" SS Bbl as well as a Mk II bushing. About every 3d. shot or so the trigger does not reset after chambering a fresh round. Replaced parts one at a time back to original config. still doing it. So obviously something didn't go back together right, I'm having trouble finding my error. Anybody familiar enough to give a little insight on what detail is being overlooked ? Thanks

Did you over adjust the overtravel screw? I believe that will cause the trigger to not reset.

Try this site, there is a troubleshooting section besides detailed assembly photos.
