Geissele Automatics B-G2S-E Geissele 2 Stage Enhanced Trigger

The Geissele Automatics B-G2S-E is a two-stage AR-15 trigger designed to deliver precise shot control without the premium price tag usually attached to Geissele's name. If you're building or upgrading a precision rifle—whether for competition, long-range hunting, or tactical use—this trigger gives you the crisp, predictable break and smooth takeup that separates good shooting from great shooting. The two-stage design lets you manage that first-stage take-up consciously, then break cleanly on the second stage, which translates directly to tighter groups and faster follow-up shots.

What makes the B-G2S-E a genuine value play is that it doesn't compromise on the core performance you expect from Geissele. The first stage breaks at 2.3 lbs with a smooth, controlled take-up; the second stage delivers a crisp 1.2 lb break—the kind of candy-cane feel that tells you exactly when the shot's going downrange. It's built from steel with a durable black finish, designed to handle the wear and heat of serious shooting. The kit ships complete with trigger and hammer assemblies, springs, hammer pin, grease, and installation instructions, so you've got everything needed to drop it into your receiver.

This trigger fits standard semi-automatic AR-15 and M16 receivers with .154" diameter hammer and trigger pin holes. It will also work in AR-pattern .308 rifles that accept standard AR-15 triggers, making it adaptable across multiple platforms. Whether you're fine-tuning a precision build or upgrading an existing rifle, the B-G2S-E delivers the control and reliability Geissele is known for—built to last and backed by their reputation.
