Geissele Two-Stage (GA-SD-C) Trigger Group

Geissele triggers have a reputation for reliability and great performance out of the box. If you've always felt your AR was capable of better precision this might be the ticket.

The SD-C (super dynamic combat) is a two stage 4.5lb.  fixed-weight combat trigger that allows precise and accurate trigger control. 

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.

It's got a crisp pull with a clean reset. Compared to the standard AR trigger it's like switching from a Pinto to a Porsche.
