Geissele Super MCX SSA – M4 Curved Trigger

Geissele Super MCX SSA – M4 Curved Trigger

The Super MCX SSA is Geissele’s two-stage trigger for the SIG MCX. It is derived from the Super Semi-Automatic (SSA), Geissele’s M4 carbine trigger that is safety certified by Crane Naval Surface Warfare Center, and keeps its performance, reliability and forgiving pull.

At roughly 4.5 lb total it is light enough for precise shots yet forgiving enough for fast close-range shooting, making it a good all-round trigger for hunting and practical sporting use.

• Two-stage, non-adjustable pull of approx. 4.5 lb total
• Classic M4-style curved trigger bow
• Built specifically for the SIG MCX platform
• Derived from the Crane-certified Geissele SSA
