The Geissele Super Semi-Automatic Enhanced (SSA-E) Trigger is a finely-tuned semi-automatic-only version of our full-auto, two stage combat trigger presently used in the U.S. Special Operations Community. Built on the chassis of the Geissele SSA, the SSA-E provides enhanced trigger control and weapon accuracy while maintaining the robustness and reliability of our combat-proven two-stage trigger. The SSA-E s reduced 1st and 2nd stage pull weights result in a trigger with a smooth, light 1st stage take-up and a crisp, candy cane-like 2nd stage break. 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.
Performance Advantages for the Shooter
The Geissele SSA-E has a pull weight of about 3.5 lbs. There is 2.3 lbs. on the 1st stage and 1.2 lbs. on the 2nd stage. The pull weights and sear engagement are non-adjustable by the shooter.
Trigger and hammer are made from quality tool steel.
Sear surfaces are cut by a wire edm machine. Sears cut this way are very accurate and the non-directional surface finish of the wire edm gives a smooth trigger pull without the associated grittiness of directional machining marks left by a milling cutter.
The initial force needed to start the disengagement of the sear surfaces is low and the force linearly increases at a low rate. This helps the shot to fall at the initial point of aim and aids in building shooter confidence in his weapons ability to put the rounds where his sight is pointing.
The Geissele SSA-E trigger allows the shooter to slap through the trigger pull on close in shots but also set up a long range shot with a crisp trigger break.
A full force hammer spring is used for quick lock time and positive ignition of all types of ammo. No lightened hammer spring is used.
The hammer is lighter than a standard AR15 hammer. The lightened hammer favorably decreases lock time over a standard hammer from 8.5 to 5.1 ms and increases accuracy of the weapon.
