Geissele SSA Super Semi-Automatic Two-Stage Trigger for AR-15/LR-308 - Matte Finish

The Geissele SSA Super Semi-Automatic trigger is a precision two-stage trigger built for AR-15 and AR-308 platforms. Unlike adjustable triggers that demand careful tuning, the SSA arrives ready to perform—no gunsmith visits or tinkering required. It's engineered for shooters who need a trigger that balances precision with speed: light enough for deliberate, accurate shots downrange, but responsive and forgiving enough for dynamic, close-quarters work. Whether you're running precision rifle drills, working through transitions in a tactical environment, or putting rounds on steel at the range, the SSA delivers predictable, repeatable performance across varied conditions.

Geissele's SSA has earned military validation—it's safety certified by Crane Naval Surface Warfare Center—and is trusted by law enforcement and serious shooters who depend on their tools. The two-stage design is the key: the first stage (2.75–3 lbs.) brings you into position with consistent resistance, then a short, clean second stage (1.5–1.75 lbs.) breaks the shot. Total pull weight lands in the 4.25–4.75 lb. range, giving you precision without the hair-trigger liability of a single-stage setup. All this comes in a matte finish that matches modern tactical aesthetics and resists glare.

Drop-in installation on any mil-spec AR platform—no special tools or fitting required. The curved M4 trigger bow and mil-spec pin diameter ensure compatibility with standard builds. Note: Geissele AR-15 triggers are not compatible with Sig MPX/MCX platforms or pistol-caliber carbine variants.

Frequently Asked Questions

Will this trigger fit my AR-15 or AR-308?

Yes, the SSA is designed for mil-spec AR-15 and AR-308 platforms. It drops in using the standard mil-spec pin and will not require fitting. However, Geissele AR-15 triggers are not compatible with Sig MPX/MCX weapons or pistol-caliber carbine variants.

Is this trigger adjustable?

No. The SSA is non-adjustable and comes pre-tuned from the factory. The first and second stage weights are fixed, so no tweaking or tuning is needed.

What's the difference between a two-stage and a single-stage trigger?

A two-stage trigger has two distinct phases: the first stage builds resistance and brings you into a ready position, then a shorter, cleaner second stage breaks the shot. This design allows the SSA to be light enough for precision work while maintaining safety and control during fast, tactical shooting. A single-stage trigger typically has one smooth pull from start to finish.

Is the Geissele SSA suitable for law enforcement and tactical use?

Yes. The SSA is recommended for demanding applications including law enforcement, dynamic environments, and mid-range carbine work. It's safety certified by Crane Naval Surface Warfare Center and is built to perform under real-world stress.
