The Geissele Super Dynamic-Combat (SD-C) Trigger featuring an exclusive flat trigger bow, is a rugged, nonadjustable combat trigger with a sear design that provides a wide margin of safety against unintentional discharges yet still gives the operator a sharp, repeatable trigger release.

Note: This trigger is designed for mil-spec AR15/M4 carbine rifles and uses a standard Mil-Spec pin size.
