Single-Stage Precision® (SSP) M4 Curved Bow
Single-Stage Precision® (SSP) M4 Curved Bow
The Single-Stage Precision® (SSP) M4 Curved Bow is a non-adjustable single-stage trigger for AR15/AR10 platforms. It suits precision, target, and dynamic shooting when the shooter prefers a pull without a separate first stage.
Single-Stage Break and Reset
There is no separate take-up to a second-stage wall. The trigger breaks after the final resistance is overcome and resets with short, distinct tactile feedback.
Construction and Installation
S7 tool-steel components are wire-EDM machined and protected by a black-oxide finish. A complete function check is required after installation.
Compatibility
Designed for mil-spec AR15/AR10 platforms using standard 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
Model 05-400 is the SSP with a classic M4 curved bow; the flat version is officially named SD-SSP and uses part number 05-483.
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.
