Not sure if its available here, but I don't see why not.

Nikon’s INLINE XR series of muzzleloading riflescopes are designed to give an edge to anyone wanting to extend their season – or their range – with a muzzleloader. The breakthrough INLINE XR riflescope technology makes 300-yard shots a reality for hunters shooting today’s increasingly accurate inline muzzleloaders.

Featuring the patented BDC 300 reticle, the ultra compact INLINE XR 3-9x40 is available in matte, silver or Realtree® APG finish. Five inches of eye relief throughout the magnification range allow the scope to be comfortably and safely mounted on even the hardest kicking muzzleloaders.

It offers precision ¼-MOA adjustments, quick focus eyepiece and light transmission boosted up to 92% for dawn to dusk brightness. The INLINE XR’s BDC 300 reticle can be fully optimized to match the drop of virtually any sabot load with Spot On™ Ballistic Match Technology. The Spot On program provides users with exact aiming points on the BDC reticle for any load or ammunition at a specified range. Spot On can be purchased for iPhone and Android or tried out for free at nikonhunting.com/spoton.
