I guess doing away with the J-Lock feature will negate any factory warranty from Remington, just like Marlin did to those who replaced the Cross-Bolt Safety on the Lever Actions.
I think the J-Lock is UGLY and is nothing more than a hindrance. It has little, if anything, to do with safety and more to do with inconvenience. IMO.
If you need a J-Lock to keep people safe around a rifle, you have more problems than a J-Lock can solve.
