Just looking at your trigger there I do believe it’s still a factory unit. Likely a 3-screw. The factory 110 3-screw triggers have a very distinct bevel on the sides of the trigger face, while the aftermarket triggers are bit more subtle. And the factory trigger is thicker through the length of the curve, while aftermarket pieces are usually thinner. This can be seen in the photo I posted in #7. But won’t know for sure until it’s removed from the stock & can be seen completely.


Even so, if you have a factory 3-screw I wouldn’t worry about it. Especially if yours already feels nice. Those triggers have potential & can be made to perform quite nicely.
