Nikon’s Inline XR riflescopes are designed to function flawlessly with modern inline muzzleloading rifles. Inline XR riflescopes use a fully multicoated optical system to ensure that your sight picture is clear, bright, and high contrast—even in early morning low light conditions. These scopes feature Nikon’s BDC 300 Reticle designed specifically for the ballistics of sabots/bullets and is compatible with Nikon’s SpotOn technology mobile app.
