The SIG MCX rifle system may not be as popular as the AR-15 yet, but it is quickly becoming a contender with companies like Geissele Automatics jumping on board and providing high quality aftermarket triggers. The Super MCX SSA trigger is inspired by the highly popular SSA AR-15 trigger and features the same combat inspired two-stage design. It retains the highly reliable and safe function that the other 4.5lb triggers provide while still being extremely smooth with a crisp break and tactile reset. It is non-adjustable to reduce any risk of malfunction or negligent discharges in high stress situations and is recommended for use by law enforcement during CQB situations, home defense, or even hunting applications. The Super MCX Trigger is a great all-around trigger that will greatly increase the functionality of your SIG rifle for any situation.

  • Installs with standard MCX pins
  • Works with SIG MCX rifle systems
  • Designed for law enforcement, home defense, or hunting
  • 4.5lb two stage trigger pull
  • Features a flat trigger bow for increased leverage and tactile feel
  • EDM wire cut from heavy duty S7 tool steel with black oxide finish

Note: Trigger pull weights are approximate and may vary slightly between rifles.

The Super MCX SSA trigger is easy to install, if a little more time consuming than an AR-15, but the end result is a trigger that is miles better than the stock trigger. It features a flat trigger bow that helps to increase leverage when pulling the trigger and gives you a more consistent trigger pull. Each trigger is precision EDM wire cut from heavy duty S7 tool steel with a durable black oxide finish giving you the reliability and durability you can depend on.

Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.
