Product Overview and Introduction

Experience the gold standard of combat-proven reliability and tactical precision with the Geissele Automatics Super Semi-Automatic (SSA) Two-Stage Trigger featuring a traditional Curved Bow and a robust 4.5 lb Total Pull Weight – MPN: 05-101. Widely recognized as the premier non-adjustable combat trigger for the AR platform, the SSA is specifically engineered to handle the harshest operational environments while offering a refined, predictable two-stage pull that dramatically improves accuracy.

Whether you are equipping a hard-use law enforcement patrol rifle, a home-defense carbine, or a reliable duty-grade AR build, the SSA delivers a smooth first-stage take-up followed by a clean, crisp second-stage break that gives you absolute confidence when it matters most.

Combat-Ready Two-Stage Engineering

Engineered to exacting military specifications, the SSA combines rugged durability with superior internal geometry:

• Robust Duty Pull Weight: Factory-tuned to a total pull weight of approximately 4.5 pounds (roughly 2.75 lb first stage and 1.75 lb second stage), providing an ideal safety margin for high-stress environments while remaining exceptionally crisp.

• Controlled Second-Stage Break: Designed with a clean, predictable break that eliminates creep and helps you place accurate shots precisely where intended.

• Traditional Curved Match Bow: The classic curved trigger face provides a natural, comfortable finger placement surface for a familiar and consistent pull.

• Full-Power Hammer: Utilizes a robust, full-weight hammer to ensure 100% reliable primer ignition across all commercial, duty, and military-spec ammunition types without light strikes.
