Geissele Automatics AR-15 Super Dynamic Combat Trigger

The Geissele Super Dynamic Combat (SD-C) Trigger is a high-performance, duty-ready upgrade for your AR-15 or AR-10 rifle. Designed with reliability and control in mind, it features a flat-faced trigger for improved leverage and feel, helping you maintain control under pressure while still enjoying a smooth, responsive pull.

This trigger installs just like a standard Mil-Spec unit and fits any .223/5.56 or .308 rifle using a Mil-Spec lower receiver with .154" trigger pins. Built from EDM wire-cut tool steel and finished in black for durability, it’s made to perform in even the most demanding situations.

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

Features:

• Fits all Mil-Spec AR-15 and AR-10 lowers
• Uses standard .154" trigger pins
• Flat trigger bow for better control and faster resets
• 4.5 lb total pull weight – tuned for safe, confident operation
• Smooth and consistent two-stage break
• Non-adjustable sear design for increased safety margin

Precision machined from tool steel with a durable black finish
The SD-C is a non-adjustable two-stage trigger with a 4.5 lb total pull, giving you a deliberate, predictable break that helps prevent accidental discharges in high-stress environments—perfect for duty, home defense, or tactical use.
