The Geissele Super 3 Gun S3G Hybrid AR-15 Trigger is the perfect addition to your AR-15 rifle. This trigger provides a clean, crisp, and consistent trigger pull that is sure to improve your shooting experience. The S3G trigger uses a Colt large pin .170” trigger and hammer pin so it will NOT fit in any Mil-Spec stripped lower receiver. It features a curved trigger bow that gives you optimum trigger control and ergonomics. Not only does it work in 5.56 or .223 AR-15 rifles, but it also works in .308 AR-10 pattern rifles. Each trigger is precision EDM wire cut from heavy duty tool steel with a durable black finish giving you the reliability and durability you can depend on.


  • Trigger pull weights are approximate and may vary slightly between rifles.
  • NOT compatible with receivers lowers

The Geissele Super 3 Gun (S3G) Trigger is the perfect choice for competition use where fast follow-up shots and quick target acquisition are required. It features a hybrid single stage trigger that maintains the safety and reliability of a two-stage trigger while still being extremely light and smooth. The short pull and quick reset make it easy to shoot your semi-automatic rifle fast and accurately.
