The Element Semi-auto shotgun brings together the signature fit and finish of a Weatherby, with an "inertia-operated" action. The result is performance that is clean, smooth, and ready for round after round of high volume shooting. In 2016, the Element was awarded the NRA American Hunter Golden Bullseye for Shotgun of the Year. The Element Deluxe features Weatherby's Intergral Multi Choke System. The IMC choke tube thread pattern is compatible with the following choke tube patterns: Browning Invector (not Plus), Mossberg Accu-Choke and Win-Choke.FeaturesAircraft grade aluminum receiverDrop-out trigger systemDual purpose bolt releaseChrome-plated boltInertia-operated actionChrome-lined barrelIntegral Multi Choke System
