Geissele’s Super MCX SSA Curved Trigger brings the precision, smoothness, and reliability of their original Super Semi-Automatic trigger for the AR-15 platform to the SIG Sauer MCX rifle. This combat/competition-ready two-stage trigger is designed for both deliberate, aimed fire and snap shooting.
The Super MCX SSA Curved Trigger packs a fixed 4½ lb. total pull weight with non-adjustable sear engagement. The first stage of the pull builds gradually to 2½ lbs - so you can pre-stage precision shots - followed by a 2 lb. second stage with a nice, crisp, snappy let-off. A full-power spring the Super MCX SSA drives the lightweight hammer forward at high velocity to speed up lock-time and deliver reliable ignition of all types of ammo. Reset is fast and positive, so you’re ready for that critical follow-up shot without losing focus on the target.
This version of the Geissele MCX Super SSA trigger has a smooth, curved, .285" wide trigger face that provides comfortable, natural finger contact for excellent control, even during long, rapid-fire shooting sessions. Versions are also available with a standard mil-spec M4 curved shoe or a flat face that some target shooters prefer.
