Geissele Single-Stage Precision (SSP) M4 Curved Bow Trigger 05-400

The Geissele Single-Stage Precision (SSP) M4 Curved Bow Trigger 05-400 is a single-stage trigger designed specifically for compatible AR-platform configurations. The Geissele SSP trigger features a curved M4-style trigger bow and a drop-in design intended to simplify installation compared with multi-component trigger assemblies.

Unlike a two-stage trigger, the Geissele SSP trigger uses a single-stage pull with no defined first-stage take-up. The design provides a consistent trigger interface and a distinct reset, giving users clear tactile feedback when operating the trigger. Its single-stage configuration makes it a straightforward option for AR-platform builds where this trigger format is preferred.

The Geissele single stage trigger is manufactured using S7 tool steel, a material selected for its suitability in demanding mechanical applications. Components are precision machined using wire EDM manufacturing technology, allowing Geissele Automatics to produce the trigger components to the required specifications.

For long-term protection, the trigger components receive a black oxide finish designed to provide corrosion resistance while maintaining the assembly's black appearance. The combination of S7 tool steel construction, precision machining, and protective finishing reflects Geissele Automatics' approach to manufacturing AR-platform components.

The curved M4 trigger bow provides a familiar interface for users accustomed to conventional AR-style trigger geometry. Its drop-in format and single-stage configuration make the Geissele SSP trigger suitable for compatible builds where a compact, purpose-built trigger assembly is required.
