Formidilosus,

Negative, the trigger was installed correctly. That trigger has had maybe 1500 rounds through it over the last three years just in the LEO drills and my son shooting it for practice.

When I got the rifle from him it was working perfectly. He said he cleaned it and noticed the disconnect spring appeared to be setting crooked in the disconnect. After he cleaned it it worked perfectly, I shot it myself for 100 rounds. The disconnect spring is installed correctly, with the large end down.

My guess is that a piece of primer or other debris got under the disconnector or the trigger itself.

The trigger is most likely fine, but I cannot trust it at this time. I am sending it back to Geissele and have them look it over and test it for function.

I know the Bushmaster trigger works.
