The SSA-E's reduced first and second stage pull weights result in a trigger with a smooth, light first stage take-up and a crisp, candy cane-like second stage break.It has a simple design similar to the original M16 trigger. There are no adjustment screws to come loose and all springs are captive, they will not get lost during disassembly. The entire trigger can be disassembled for cleaning and can be installed without removing the safety.The SSA-E is ideal for use in precision Squad Designated Marksman type rifles where weapon accuracy and reliability are critical and a non-adjustable drop-in trigger is desired.
