Geissele Super MPX SSA Trigger

The Geissele Super MPX SSA is a high performance combat inspired two stage trigger for SIG SAUER MPX Platform. It is CRANE safety certified M4 carbine trigger, The Super Semi Automatic (SSA) and the Super MPX SSA features the same performance, reliability and safety. It is a non-adjustable, two stage trigger that provides the user with precise and accurate trigger control. 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.
