Pinch point! - Mesa Tactical High-tube Tele Collapsible Shotgun Stock Adapter

This is the adapter Remington uses for the factory arm brace version. I have this and the full SB arm brace kit. The SB full kit comes with an adapter, much superior to this. At the thumb/socket point this adapter has a terrible pinch point, the angle of the adapter face to 870 base is incorrect, therefore the angle of the brace tube is incorrect. Not only does this create the pinch point it does not provide the correct sight alignment... I have this adapter for sale...
