Geissele Automatics AR-15 Super Dynamic Enhanced Trigger

The Geissele SD-E (Super Dynamic Enhanced) Trigger is a high-performance, two-stage trigger designed to significantly improve the accuracy and feel of your AR-15 or AR-10. Engineered for precision and target shooting, it’s a direct upgrade that installs just like a standard Mil-Spec trigger.

One of its standout features is the flat trigger bow, which gives you more leverage. This not only reduces the perceived pull weight, but it also provides enhanced tactile feedback, so you can clearly feel the reset and take faster, more controlled follow-up shots.

Features:

• Uses Mil-Spec .154” trigger pins for maximum compatibility with lower receivers
• Works with 5.56/.223 and .308 AR pattern rifles
• Designed as a target and precision trigger
• Smooth, consistent two-stage trigger pull
• Has a 3.5lb total trigger pull weight
• EDM wire cut from heavy duty tool steel
• Features a flat trigger bow that reduces perceived trigger weight and improves tactile feedback

The SD-E trigger is compatible with both 5.56/.223 and .308 AR-pattern rifles and uses standard .154-inch trigger pins, ensuring it will fit most Mil-Spec lower receivers. Built for durability and reliability, it’s precision-crafted using EDM wire cutting from heavy-duty tool steel and finished with a robust black coating. With a total pull weight of approximately 3.5 lbs, it offers a smooth and consistent two-stage pull.

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.
