I've done trigger jobs on at least a dozen post 64 m70s made from the mid 1970s to the early 2000s. Using the factory trigger return spring(and checking with an accurate trigger pull gauge), I was never able to get SAFE sub 3.5lb on any of them
All that means is that you need to change out the heavy lawyer spring when you are doing the trigger job. Replacing the spring is childs play.
If you want a Browning trigger buy a Browning, if you want a Remington trigger buy a Remington. Model 70's should have the classic model 70 trigger (just do a better job of making it than some of the late Conn. guns!)......................DJ
