Frequently Asked Questions

Why do Sig MPX triggers need a special design like the Timney MPX trigger?

The Sig MPX has a very fast cyclic rate and high bolt velocity due to its piston system. This rapid action can severely stress and damage standard AR-15 triggers. The Timney MPX trigger includes a unique 'trigger bridge' designed to absorb these impacts, preventing premature wear and ensuring reliability.

What are the available options for the Timney MPX trigger?

The Timney MPX trigger is offered in both single-stage and two-stage configurations. Additionally, customers can choose between a curved trigger bow or a flat trigger bow, allowing for personalization based on shooting preference and ergonomics.

How is the Timney MPX trigger installed?

Installation is a drop-in process. After separating the upper and lower receivers and removing the factory trigger, the Timney MPX trigger module is installed. It's secured by two internal screws that engage a nylon dowel to prevent them from backing out. A roll pin punch may be needed for the safety selector.

What is the typical trigger pull weight for the Timney MPX trigger?

The Timney MPX trigger is advertised with a 3-pound pull weight for the single-stage model. In testing, the curved bow single-stage version measured approximately 3 pounds 4 ounces right out of the box, indicating a light and crisp pull compared to the factory trigger.
