  1. This is the sight base ... review by LOUIS on 6/27/2017

    This is the sight base that you will need for the Remington 540X and the Williams FoolProof Target Deluxe. This base is @.160\" wide, and it allows the FP aperture to be centered over the bore. The original Remington base is @.280\" wide, which ends up with the FP aperture needing to be moved right about a quarter of the travel. I recommend that you buy the FP Deluxe and the base together to save on shipping (almost $10 for the base alone!).
