Barrel is grossly misaligned with the barrel channel and as the screws are tightened, the barrel is being drawn along the inside of the barrel channel. This pushes the side of the stock out and the barrel in the opposite direction. This is major bad news. The barrel is bent and is rubbing the barrel channel as above. Bent guard screw.
Composite material is overlaid along the receiver pathways in the V block.
The bottom line is if there is barrel springing, it is a job for Remington to replace the components or repair them as necessary.
