The Geissele Super MPX SSA Trigger 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. The Super MPX SSA is finished in Nanoweapon, a proprietary Geissele coating that provides greater wear and corrosion resistance versus other types of finishes. Due to the harsh operating system of the MPX platform we found Nanoweapon to be ideal for this application. Geissele Super MPX SSA, M4 Curve Trigger Bow 16-025
