Geissele Super Semi-Automatic Trigger | SSA

The Geissele Super Semi-Automatic (SSA) Trigger is a non-adjustable, two-stage trigger designed for AR-15 and AR-10 platforms. It provides a consistent trigger pull with a defined first stage followed by a controlled second stage break, supporting reliable operation across a wide range of shooting applications.

Featuring a traditional curved (M4-style) trigger bow, the SSA is built for compatibility with standard mil-spec lower receivers. Its two-stage design offers a balance between control and pull weight, making it suitable for general-purpose use where consistent trigger performance is desired. This trigger is not compatible with Sig MPX, MCX, or pistol caliber carbine AR variants.
