Geissele Single-Stage (GA-SD-3G) Trigger Group

Out of stock

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 SDF-3G (super dynamic 3 gun) is a 3.5-4lb. (spring dependent)  fixed-weight combat trigger that allows precise and accurate trigger control. 

The Geissele Super Dynamic 3 Gun (SD-3G) Trigger is based on the S3G Trigger. Like the S3G, the SD-3G has a shortened pull length and a lightning-quick reset to give it a unique, hybrid trigger pull that is a cross between a traditional two-stage and single-stage trigger while still retaining the safety and robustness of a two-stage combat trigger. The SD-3G’s flat trigger bow further enhances the trigger’s performance by reducing the perceived pull weight and improving the trigger’s tactile feedback to the operator making it ideally suited for 3 Gun competition shooting.

The SD3G trigger has a very short, light pull and reset. We do not recommend it for duty use, bench rest, accuracy work or shooting small groups. It is designed for close course competition use where rapid target engagement with quick follow up shots are required. * COLT 901 RIFLE USERS PLEASE SEE ARMORS TOOLS FOR PINS (PART# 02-269) THAT WORK WITH THE WIDER RECEIVER

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.
