The Geissele Super Semi-Automatic (SSA®) trigger is derived from Geissele’s Super Select-Fire trigger but designed exclusively for semi-automatic use. It features a non-adjustable, precise two-stage mechanism, enabling precise control over the trigger in various conditions and scenarios. With its two-stage design, the SSA offers a balance between lightness for accurate shots and forgiveness for rapid close-quarter engagements. Certified for safety by the Crane Naval Surface Warfare Center, it is ideal for rigorous applications like law enforcement, dynamic environments, and mid-range carbine operations.
