Geissele Single-Stage (GA-S3G) Trigger Group

In 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 S3G (super 3 gun) is a 3.5-4lb. (spring dependent)  fixed-weight combat trigger that allows precise and accurate trigger control. 

The Geissele Super 3 Gun (S3G) is a semi-automatic, hybrid cross between a single-stage trigger and a traditional 2-stage trigger. Its robust feel and light pull weight, combined with a lightning-quick reset, make this trigger ideal for any 3 Gun competitor.

The S3G 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.
