Without a doubt, the Browning Cynergy began as the most technologically advanced over and under shotgun available. The Cynergy boasts an ultra-strong MonoLock Hinge with 300% more pivot surface area to distribute wear. It has the lowest profile receiver of any 12 gauge over and under that reduces muzzle jump and perceived recoil. The exclusive Reverse Striker ignition system with mechanical triggers and a rifle-type striker provide faster locktime and reduced overtravel, while Impact Ejectors feature dual springs for positive, consistent ejection. Each Field model is given a silver nitride finish, an ultra-low profile, and high-relief engraving. Other features include a vent rib barrel and three Invector-Plus choke tubes on 12 gauge and 20 gauge models with standard Invector chokes on the 28 and 410 models.
