The SSA-E X with Lightning Bow trigger is no longer exclusive to the Super Duty line of firearms! The SSA-E X features a Nanocoated wide body trigger and Nanocoated Hammer, with a special Chrome Nitride disconnect that combines advancements in coating design to bring about the next evolution of the venerable SSA-E. These coatings dramatically enhance wear and corrosion resistance and keep the trigger running smooth and breaking clean even after heavy use with minimal lubrication.  The SSA-E X with Lightning Bow trigger is a non-adjustable trigger, with pull weights that result in a trigger with a smooth, light first stage take-up and a crisp, candy cane-like second stage break. The SSA-E X is ideal for use in precision Designated Marksman type rifles where weapon accuracy and reliability are critical and a non-adjustable drop in trigger is desired.
