B-Square introduces a shotgun scope combo mount that is easy to install on most popular shotguns. It features a sturdy 2 1/2-inch by 20-inch scope with high-definition, fully-coated lenses to provide a sharp image even in low light. Designed to withstand the recoil of a slug gun, the scope also features standard shotgun 6-inch eye relief and a duplex reticule. The shock-proof, fog-proof, waterproof, nitrogen-filled scope has a 1-inch tube and is available in black or Mossy Oak break up camouflage. Made from lightweight aircraft aluminum, the saddle-mount and rings require no gunsmithing to install and use available hardware on the shotgun.
