Re thinking the conversion of the L&R set trigger for the CVA Frontier. A final check of the possible problems showed that the trigger bow is not deep enough to accommodate the L&R trigger set.
So, Now I'm back to considering the solution offered by
@Winterhawk involving stripping the frontier set trigger down and leave just the front trigger but move it back closer to the sear arm. Of course the front trigger works well as it is although a bit heavy. Moving it back will lighten the pull and place the trigger in a better position.
Now trying to calculate the best place to drill. Only get one shot at it.
