I just installed a Rifle Basix trigger in my 110 and I am NOT pleased. They sent cup point set screws instead of flat point. Cup points are used to lock down on a shaft. The location of the sear engagement screw is too far from the notch on the trigger allowing the sear to become trapped between the notch and screw. This gives a notchy pull. As for the "instructions" the less said the better. No clue as to adjustment. In short I should have burned that $100 bill and saved myself some time.
