My first thought was Timney but its not listed, is this a new model browning rifle? It took Timney a year or so to come up with a trigger for the xbolt...
The standard trigger is 4.25 pounds. (The AB stands for A Bolt.) The AB3 is an entry level hunting rifle. 4-1/4 pounds is light enough for that kind of rifle.
There is a trigger spring kit though that drops the pull pretty much in half. https://www.mcarbo.com/browning-ab3-trigger-spring-kit.aspx
I didnt realize you were talking a Abolt. T. O'Heir is right, there is a spring kit that will lighten the trigger pull but as far as I know there are no aftermarket triggers for the A bolt. Even thought the x bolt came with a adjustable trigger I opted for the Timney trigger when it became available..
