The Geissele Super Semi-Automatic (SSA) - Large Pin Trigger 05-123 is a non-adjustable, two-stage trigger designed for compatible AR-platform rifles using large-pin lower receivers. Developed by Geissele Automatics, this semi-automatic-only trigger is based on the company's Super Select-Fire trigger design.
The Large Pin Trigger features a two-stage configuration with a defined first stage followed by a distinct second-stage release. Its non-adjustable construction keeps the trigger settings fixed at the factory, providing a straightforward configuration without user-adjustable pull weight or engagement controls.
The SSA trigger is designed specifically for semi-automatic operation. Its two-stage layout provides a clearly defined sequence through the trigger pull, making it distinct from single-stage trigger designs. The large-pin configuration is an important consideration for compatible AR-platform applications, as it is designed around receivers using larger-diameter trigger and hammer pins.
This version incorporates Geissele Automatics' established SSA trigger architecture while adapting the assembly for large-pin applications. The platform-specific configuration makes it different from standard-pin SSA variants and allows it to be used with compatible large-pin lower receivers.
The Super Safety Geissele Trigger terminology is sometimes used when discussing Geissele trigger products, but the SSA Large Pin is specifically a semi-automatic trigger assembly. Its fixed two-stage configuration and large-pin geometry define its intended application.
With its two-stage design, non-adjustable configuration, and large-pin specification, this Geissele Super Semi-Automatic (SSA) trigger provides a dedicated option for compatible AR-platform rifles requiring a large-pin trigger assembly.
