The Geissele Super Dynamic Combat Trigger, known as the SD-C (brand part no. 05-165), pairs an exclusive flat trigger bow with a rugged, non-adjustable combat-grade design. Geissele Automatics engineered the sear geometry to provide a wide margin of safety against unintentional discharges while still giving the shooter a sharp, repeatable trigger release. Because it is non-adjustable, there is nothing to work loose or drift out of spec under hard use, which makes it a solid choice for a duty rifle or a home-defense carbine that needs to be dependable every time. It is a drop-in AR-15 trigger built for shooters who prioritize reliability over competition-tuned lightness.
