Geissele SD-C Super Dynamic Combat Two Stage Flat Trigger AR-15 AR-10

The Geissele Super Dynamic Combat SD-C is a semi-automatic-only, non-adjustable two-stage trigger for AR-15 and AR-10 rifles. It is derived from a select-fire trigger Geissele makes for U.S. Special Operations customers and is intended for close quarters battle, mid-range carbine work, and squad designated marksman rifles.

The trigger is made from tool steel with wire EDM cut sear surfaces and has a black finish. Total pull weight is 4.5 lb, with a 2.5 lb first stage and a 2 lb second stage. The flat trigger bow gives a consistent feel regardless of finger placement and sits 0.141 inch forward of a standard AR-15 trigger for increased reach. Installation instructions are included.
