The MPX SSA triger is currently avaible in the M4 curved configuration.
Geissele Automatics also has plans to produce the MPX SSA trigger in the flat bow and Geissele curve styles too.
Geissele Automatics states “The Super MPX SSA was designed as a high performance, combat inspired two stage trigger for the SIG SAUER MPX Platform.
Derived from our CRANE Safety Certified M4 carbine trigger, the Super Semi-Automatic (SSA), the Super MPX SSA delivers all of the same performance, reliability, safety and forgiveness features that the SSA possesses.
The Super MPX is a non-adjustable, two stage trigger that provides the shooter with precise and accurate trigger control.
The trigger is light enough to be used in competition, but is forgiving enough to be used in demanding applications such as close quarter battle (CQB) scenarios.
These features make the Super MPX ideal for competition and target shooting applications and makes this a perfect trigger for your Sig MPX.”
