Super Semi-Automatic Enhanced® (SSA-E®) Trigger - Large Pin
Super Semi-Automatic Enhanced® (SSA-E®) Trigger - Large Pin
The Super Semi-Automatic Enhanced® (SSA-E®) Trigger - Large Pin is a two-stage trigger for compatible Colt AR lower receivers using large pins. Its lighter characteristics suit precision and DMR builds.
Two-Stage Pull Characteristics
The first stage provides controlled take-up to a clearly defined wall, followed by the second-stage break. The first stage is 2.0–2.5 lb and the second stage is 0.9–1.3 lb.
Construction and Installation
The mechanism uses the conventional separate hammer, trigger, and disconnector arrangement. Installation and the subsequent function check must follow the manufacturer's instructions.
Compatibility
Designed for compatible Colt lower receivers using large trigger pins. Verify the actual pin diameter before ordering; this version is not intended for standard mil-spec pins. Standard Geissele AR15/AR10 triggers are not intended for the SIG MPX, SIG MCX, or pistol-caliber AR carbines. Geissele offers dedicated models for these operating systems.
Practical Note from neoPATRON
Large Pin identifies the trigger-pin diameter, not the AR10 platform. Verify the actual lower-receiver pin configuration before ordering.
AlwaysSecond commentary: Over my shooting career, I have used and tested many triggers. And I have been shooting with Geissele triggers for over 20 years, doing both dynamic and precision shooting. What does it tell ya??? It tells ya, that there is nothing better bro! And that is simply a fact. I haven't found anything better. Back in the day, UHL triggers were excellent, but they would occasionally go full-auto (burst) and their springs would loosen up. Triggertech was also interesting, but overtuned and unsuitable for dynamic shooting; OK for precision. Hiperfire is great ... but I only discovered it at a time when I had already been running a Geissele G2S with JP springs for 10 years ... and there was no reason to change. Timney – very good triggers, but Geissele simply suited what I needed much better. My search for the holy grail simply ended with Geissele, because what Bill Geissele does, he does damn well. And this obsession of his with perfection is reflected both in the triggers and in other Geissele products, which is why the most demanding users choose them. And I am demanding. That's why for my rifle ... Geissele Automatics.

Geissele Automatics USA – uncompromising triggers and matching quality for mounts and weapons designed for special forces
How does a small family business that started in a garage in 2004 with a single Hi-Power sports shooting trigger become an absolute technological leader whose products can be found in the rifles of the world's most elite special forces (including US SOCOM)?
The answer is simple: an obsession with perfection, mechanical precision, and zero tolerance for failure. Founder Bill Geissele designed his first triggers with a single goal in mind – to achieve a perfectly clean, predictable break and a lightning-fast reset. When the US Department of Defense (DoD) noticed his triggers, a legend was born. Geissele didn't start making "fancy" accessories. He began developing systems that fundamentally increase shooting accuracy and weapon reliability in the harshest combat conditions. Today, Geissele is synonymous with the best you can mount on an AR-15 platform (and other modern weapon systems).
Who Geissele Automatics products are intended for: For military and law enforcement professionals, special forces operators, top sports shooters, and any demanding civilian shooter who knows that trigger quality and optic mount reliability directly determine whether they hit the target ... or miss.
