The Geissele Super Dynamic Combat (SD-C) Trigger 05-165 is a non-adjustable two-stage trigger designed for compatible AR-platform configurations. It features Geissele Automatics’ distinctive flat trigger bow, giving the assembly a different trigger profile from conventional curved-bow designs. The combination of a fixed configuration and purpose-built sear geometry makes this a straightforward option for users who prefer a consistent factory-set trigger. The Geissele Super Dynamic Combat trigger uses a two-stage design with a defined first stage followed by a second-stage release. Rather than relying on user adjustments, the assembly is configured at the factory to provide consistent trigger characteristics. This fixed setup also means there are no user-adjustable pull-weight or engagement settings to configure after installation. One of the most recognizable features of the Geissele SD-C is its flat trigger bow. The flat profile provides a distinctive interface and maintains a consistent contact surface for the trigger finger. For users accustomed to flat triggers, this geometry offers an alternative to the traditional curved trigger found on many AR-platform assemblies. The sear design is engineered with an emphasis on maintaining a substantial margin against unintended discharge while retaining the defined characteristics expected from a two-stage trigger. The result is a purpose-built component focused on controlled operation and repeatable trigger characteristics. The Geissele SD-C Trigger is manufactured as a rugged, non-adjustable assembly for compatible AR-platform applications. Its flat trigger bow, two-stage configuration, and fixed factory settings make it a distinct choice within Geissele Automatics’ trigger lineup.
