#2.....It isn't just Remington;
It's a wood thing. Think of the environmental changes a stock/rifle has to go through,from factory to wherever the rack is that it's going to for sale. The barrel gap being equal on both sides is,or can be a complex issue. Not every mass produced barrel to reciever is deadnuts perfect..... combined with wood movement.
Easier,and more efficient from the manufacturer's perspective to leave a "locating" pad out front on the forearm.
So,be mindful of this potential movement,especially on thin sporter forearms if you decide to de-pad it. Not sayin,"don't"..... because I feel most rigs benefit from free float. Just sayin,tread lightly before just hogging out wood.
Good luck with your project.
