excellent trigger by Robert, Verified Owner, July 17, 2024
The Geissele trigger comes complete with BCG springs to slow down the rate force that causes tear and wear on the trigger. Smooth brake, easy installation, overall very happy with my purchase

great mo trigger! by corey, Verified Owner, March 10, 2022
This trigger is a fast improvement over the stock factory trigger (non timney trigger). The added recoil springs of different strengths is nice, especially if you plan to shoot suppressed. I coupled mine with a radian safety.

Product Info for Geissele MPX M4 Trigger System

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.image
