Geissele Automatics Super Dynamic Combat SD-C Two Stage AR-15 Trigger - Flat
Details
Details
The Geissele Super Dynamic Combat (SD-C) Trigger is a duty-ready upgrade built with reliability and control in mind, giving shooters a flat-faced trigger for improved leverage under pressure without sacrificing a smooth, responsive pull.
Features:
- Two-stage design with a non-adjustable 4.5 lb total pull weight
- Flat trigger bow for better control and faster resets
- Non-adjustable sear design for an increased safety margin
- Fits any mil-spec AR-15 and AR-10 lower using standard .154" trigger pins
- Precision machined from tool steel with a durable black finish
- Built specifically for duty, home defense, and tactical use
The SD-C's deliberate, predictable 4.5 lb break gives shooters genuine protection against an unintentional discharge in high-stress environments, while the flat bow's added leverage keeps the pull feeling smooth and controlled.
Trigger pull weights are approximate and may vary slightly between rifles.
Geissele Automatics was established in 2004 with the mission to build the highest quality, reliable triggers for competition and duty use; its first design, the Hi-Speed National Match trigger, was successful enough that the Department of Defense asked the company to produce a select-fire trigger for U.S. Special Operations. That reliability shows up range trip after range trip, build after build.

My favorite long distance trigger
by walter -
The SD-C trigger is my favorite for long distance shots. The 1st stage pull is light into a good wall to rest on until the easy to predict light break of the 2nd stage. It’s got a great feel for the purpose. Geissele makes great triggers for all applications, thus just happens to be my go to for precision shooting.
I like it

Happy with this on my Go-To build
Fantastic Upgrade

I have shot other rifles equipped with this trigger and loved the way they work. It’s been on my radar list for a while and I finally made my purchase. Incredible easy to install. I watch a couple videos and had zero issues. The whole thing took less than 5 minutes. That included removing my safety selector. I don’t think I have ever shot a trigger I like better than the Geissele design. Crisp break and reset is incredibly short. Very pleased with this product.

Will fit your PSA AR-10. Easy installation. Smooth trigger pull.
This Trigger speaks for Itself

If you are building any sort of mid-high quality AR you can not sell yourself short on a crappy cheap trigger group. After doing several hours of research on triggers for my SBR build I decided on the SD-E. The experience every time I squeeze the trigger is amazing. The first stage is a stable consistent ~2.5lbs motion with a prominent end point. The second stage provides a crisp quick break. The trigger release also provides a smooth constant motion with a light audible/mechanical click right before the second stage begins. The feel and the performance is amazing. All my future builds will contain Geissele triggers.
Geissele triggers seem to be hit-and-miss
by Patrick
Note that I am not comparing this to a basic commercial "mil-spec" trigger. I am comparing it to other Geisseles. It is the fourth Geissele trigger I've owned. Of those, the SSA and SSA-E are amazing. Very smooth 1st stages, perfect breaks at 2nd stage with no noticeable creep at all. This SD-C Trigger however definitely has some creep. In fact, within that creep is a definite 'notch' I can feel right before the break. It's very annoying when trying to squeeze off a shot carefully. I know it's a "combat" trigger and not a match/precision trigger. But this example is noticeably inferior to its close relative and functional equivalent, the SSA. In fact, I prefer the pull of my ALG ACT trigger over this one's.
well worth the money

Awesome upgrade over the standard mil-spec trigger.
The perfect trigger
by Casey King
This is the best trigger on the market. Geissele smooth, light and responsive but not too light. The flat trigger face aids in a straight pull.I've been looking for this exact trigger everywere Thanks Primary!!!
