The Viper Shadow Express has the power and penetration needed for hunting small game at medium-to-close ranges, making it a powerful pest control tool for your home, barn or garden. Adding a Crosman Nitro Piston delivers more benefits.

It's easy to switch back and forth between pellets and shotshells to optimize your hunting. The Shadow Express has an all-weather synthetic stock with a molded cheekpiece on both sides, making this a truly ambidextrous gun. The grip and forearm are texturized to give you a better hold, while the ventilated rubber buttpad absorbs recoil.

Here are the benefits of getting a Viper Shadow Express with a Crosman Nitro Piston conversion:
  • Smoother cocking
  • Smoother shooting
  • No spring torque
  • No spring fatigue, even if you leave it cocked for hours
  • Functions perfectly in cold weather
  • Lasts longer than a metal spring
  • Installed by our expert gunsmiths!
  • NOTE: Installation of the Crosman Nitro Piston will delay shipment by 24 hours (or one business day)
Installation of the Crosman Nitro Piston has a 1-year warranty.
