Geissele Super MPX SSA - M4 Curved Trigger

High-Performance Trigger for SIG SAUER MPX

The Geissele Super MPX SSA is a non-adjustable, two-stage trigger designed for the SIG SAUER MPX platform. Derived from the CRANE Safety Certified M4 carbine trigger, the Super Semi-Automatic (SSA), this trigger provides the same precision, reliability, and safety while being adaptable for competition or dynamic close-quarter applications.

Key Features

• Two-Stage Design: Delivers precise and accurate trigger control for competition or tactical scenarios.
• Forgiving Operation: Light enough for competition but robust for high-stress, fast-paced environments.
• Versatile Performance: Perfect for target shooting and competition on the SIG MPX platform.

Geissele MPX Recoil Springs

Extensive testing revealed the high bolt speed in MPX systems can impact component longevity. To address this, Geissele includes three recoil spring options with varying strengths (30%, 45%, and 55% stronger than the stock spring) to optimize performance based on the ammunition used.

Spring Selection Guide

• Yellow Spring: Start with this spring and test functionality for general-purpose ammunition.
• Red Spring: Use for lighter spring rates if bolt lock-back or ejection issues occur.
• White Spring: Select for heavier spring rates to reduce perceived operating system violence while maintaining functionality.

Why Choose the Super MPX SSA Trigger?

The Geissele Super MPX SSA is an ideal upgrade for the SIG SAUER MPX platform, offering precision and reliability for competition and target shooting. The included recoil spring options provide enhanced customization, ensuring optimal performance for every shooter.
