I just didn't like the Mossberg Trigger and replaced it with a Timney trigger. After, receiving it back from Mossberg The trigger still started clicking occasionally. But, never locked up. The fear of locking up and Clicking just screwed me up. The new trigger is so nice I crisp , clear trigger pull Now. It totally improved my Groups. I can put 5 rounds Within a half inch at 100yds. One screw and 5 minutes And it was changed.
