I don't think there are a great amount of variations in rifle scope erector systems. Some have a single leaf spring or a double leaf or even coil springs holding the tube in place along with the turret(s). This is either a QC issue or poor quality components or both IMHO. Leupold is probably making many more scopes than their"glory years" and are also making other items they did not make 30-40 years ago. Maybe the business has gotten out of hand or the owners want more $$ and are allowing corners to be cut.
