Geissele Super Semi-Automatic (SSA®) Trigger
The Geissele Super Semi-Automatic (SSA®) is one of the most respected two-stage AR triggers ever produced. Originally developed from Geissele's legendary Super Select-Fire® trigger, the SSA was designed to provide the precision of a match trigger while maintaining the reliability and safety required for duty use.
Its non-adjustable two-stage design offers a smooth, predictable first stage followed by a clean, crisp second-stage break, giving shooters greater control for precision shots without sacrificing confidence during rapid engagements.
The SSA is Crane Naval Surface Warfare Center safety certified and has earned the trust of military units, law enforcement agencies, and professional shooters around the world.

Our Thoughts
While we're generally fans of high-quality single-stage triggers, we completely understand why so many shooters continue to prefer a well-designed two-stage trigger.
And if you're looking for one, the Geissele SSA is one of the very best.
Its first stage is smooth and predictable, allowing you to prep the trigger as you build your sight picture before breaking a clean, consistent second stage. The result is a trigger that excels at both precision shooting and practical defensive use.
The SSA has been fielded by military and special operations units across the globe for years, and that pedigree is immediately noticeable the first time you shoot one.
SSA vs. SSA-E
Choosing between the SSA and SSA-E really comes down to your intended use.
SSA
-
Slightly heavier pull weight
-
More forgiving under stress
-
Ideal for duty rifles, defensive carbines, and general-purpose builds
SSA-E
-
Lighter second-stage break
-
Easier to shoot rapidly with minimal effort
-
Better suited for precision work, competition, or shooters who prefer a lighter trigger
If you're building a rifle intended for hard use, defensive applications, or simply want a trigger that still feels "duty-ready," we recommend the SSA.
If you're chasing maximum precision, faster split times, or simply enjoy a lighter trigger pull, the SSA-E is an outstanding option.
AR-10 Compatible
Another advantage of the Geissele SSA platform is its compatibility with both AR-15 and AR-10 rifles, making it an excellent upgrade regardless of which large-frame or small-frame rifle you're building.
Final Verdict
The Geissele SSA has become the benchmark by which premium two-stage AR triggers are measured. It combines military-proven reliability with exceptional trigger feel, making it equally at home on duty rifles, defensive carbines, precision gas guns, and competition builds.
If you want a trigger that inspires confidence without sacrificing durability, the Geissele SSA remains one of the finest upgrades you can install in your rifle.
