Geissele Super Semi-Automatic SSA Trigger - AR-15 Two-Stage (05-101)

The two-stage trigger that changed what shooters expect from a fighting rifle — the Geissele SSA is the standard others chase.

The Geissele Super Semi-Automatic (SSA, 05-101) is a precision two-stage combat trigger: a smooth, deliberate first-stage take-up followed by a crisp, predictable second-stage break. That two-stage discipline lets you prep the trigger under stress and commit only when the sights say so — the reason two-stage designs dominate serious duty and DMR use. The SSA is the semi-automatic-only descendant of Geissele's select-fire SSF trigger, built for hard use with full-power springs for absolutely reliable ignition.

Machining, materials and quality control are where Geissele earned its name: every trigger is built to tolerances that make the pull feel identical on round one and round ten thousand. Non-adjustable by design — nothing to drift, nothing to come loose.

Why shooters choose the SSA

• Two-stage combat design — prep the take-up, break with certainty
• Semi-auto descendant of the select-fire SSF — genuine military lineage
• Full-power ignition reliability — duty ammunition, every time
• Non-adjustable, nothing to drift — set for life at the factory
• Made in the USA
