Geissele Automatics was established in 2004 as a manufacturer of trigger mechanisms for the AR-15 rifle. Rely on Geissele when you expect superior performance, quality, and reliability.

This is a semi-automatic-only derivative of the two-stage Super Select-Fire (SSF) combat trigger that Geissele Automatics produces for customers in the U.S. Special Operations Community.The large pin dimension is 0.169 inches, whereas the standard pin dimension is 0.155 inches. The S3G was developed to combine the SSF combat trigger’s match-grade semi-automatic performance with its smooth single-stage full-automatic feel to make a fast, smooth, and robust trigger ideal for 3 Gun competition shooting.
