Geissele Super Dynamic Combat SD-C Trigger - AR-15 Flat Bow (05-165)
£289.00
Product Overview
The SSA's combat pull behind a flat bow — the SD-C changes how the trigger meets your finger, not how it breaks.
The Geissele Super Dynamic Combat (SD-C, 05-165) pairs the proven SSA two-stage combat pull with Geissele's flat trigger bow. The flat shoe gives a consistent finger position and a mechanical advantage that makes the pull feel lighter and more controlled, while the distinct 90-degree break point sharpens your sense of exactly when the shot will fire.
Underneath, it is all SSA: smooth first-stage take-up, crisp second stage, full-power ignition springs and the combat-grade safety margin that makes Geissele two-stages the duty standard. If you have never run a flat bow, the SD-C is the definitive introduction.
Why shooters choose the SD-C
- Flat trigger bow — consistent finger placement, improved leverage
- SSA two-stage combat pull — the proven duty architecture
- Distinct 90° break geometry — you know precisely when it fires
- Full-power ignition reliability — duty ammunition, every time
- Made in the USA

Product Questions
Which receivers will the SD-C fit?
It is a drop-in trigger for AR-15/M4 pattern lowers with mil-spec trigger pins. Large-pin receivers are not compatible, so check your pin holes before ordering. If you are unsure, measure them or contact us with the receiver make and model.
What kind of shooting is the SD-C intended for?
The C stands for combat: it is the two-stage Super Dynamic set up for duty and general-purpose use, with a deliberate first stage and a defined wall rather than the lightest possible break. That makes it forgiving under stress and when wearing gloves. It still gives you the flat bow and the clean second stage that the Super Dynamic line is known for.
Why a flat bow rather than a curved trigger?
A flat shoe keeps the finger at a fixed distance from the pivot no matter where it contacts, so the perceived pull weight stays consistent. Shooters with larger hands or a lower finger placement often prefer it. If you want a lighter feel from the same flat-bow layout, the SD-E is the enhanced version of the same idea.
Do I need extra parts, and how does it sit in the range?
It installs with standard trigger and hammer pins, so no additional hardware is required if yours are in good order. There is one configuration, so there is no variant to choose between. Our Geissele Automatics collection shows how the SD-C sits between the entry-level and fully adjustable models.
What are the postage and returns arrangements?
This trigger ships from the United Kingdom with free tracked UK delivery, and tracking is emailed once it is on its way. If it does not fit your lower, see our returns policy or contact us and we'll help sort it.
