Umarex Trigger on Umarex Surge Max Elite is similar to ...?

Looking into modding my Umarex Surge Max Elite (.22) to make the trigger lighter than the 4.75 pound pull. I've already slightly rounded the trigger adjustment screw and this seems to have reduced or smoothed out the first stage pull. So...before I tackle this, I'm wondering if the trigger is similar to other Umarex break barrel models out there. If so, I can find an online trigger mod vid to go by.
