Geissele Super Semi-Automatic (SSA) Trigger
The SSA is the semi-automatic version of Geissele’s Super Select-Fire trigger. It is a non-adjustable two-stage trigger: light enough for accurate, precise shots but forgiving enough for fast close-range work, and it has been safety certified by Crane Naval Surface Warfare Center.
A good fit for hard-use and dynamic sporting rifles and mid-range carbine shooting.
- Two-stage, non-adjustable pull of approx. 4.5 lb total
- Classic M4-style curved trigger bow
- Safety certified by Crane Naval Surface Warfare Center
- Drop-in for AR-15 and AR-10 lower receivers with mil-spec pins
Designed for mil-spec AR-15/M4-pattern rifles. Not compatible with SIG MCX/MPX rifles or pistol-calibre AR-15 variants (fitting it to these voids the Geissele warranty). For the SIG MCX see the Super MCX SSA. Flat-bow and lighter “Enhanced” versions (SD-C, SSA-E) are also made.
