Geissele Super Semi-Automatic (SSA) Trigger – AR-15/AR-10

The Geissele Super Semi-Automatic (SSA) trigger is a precision two-stage trigger designed for AR-15 and AR-10 platform rifles where control and consistency matter. It features a clean 2.5 lb first stage take-up followed by a crisp 2 lb second stage break, giving shooters a total pull weight of approximately 4.5 lbs. This two-stage design allows positive trigger reset and controlled shot placement for precision shooting, 3-gun competition, and general-purpose use where reliability and accuracy are both priorities.

Manufactured from S7 tool steel with a manganese phosphate finish for corrosion resistance and durability, the SSA is a drop-in trigger that requires no permanent modification to your lower receiver. Installation requires basic AR armorer knowledge and standard punches. Each trigger is hand-tested at Geissele before shipping to ensure proper function and break quality.
