Geissele SSA-E X Enhanced 2-Stage Trigger with Lightning Bow

Geissele SSA-E X 2-Stage Enhanced Trigger with Lightning Bow
Precision meets durability in a modernized tactical trigger

The Geissele SSA-E X Trigger combines the proven design of the SSA-E with advanced features tailored for shooters demanding reliability and precision. Built on the SSA-E platform—a trusted trigger used by military snipers and competition shooters—it retains the hallmark two-stage pull: a smooth 2.0-2.5 lb first stage and a crisp 0.9-1.3 lb second stage. This design delivers exceptional shot control and consistent break, critical for high-pressure tactical and competitive applications.

What sets the SSA-E X apart is its Lightning Bow® trigger. This flat-faced, semi-curved design enhances ergonomics and control, bridging the gap between traditional curved triggers and modern flat profiles. The addition of a Nanoweapon coating, a state-of-the-art Diamond-Like Carbon (DLC) finish, protects against wear, corrosion, and fouling while requiring minimal lubrication. These upgrades make the SSA-E X ideal for demanding conditions where durability and precision are paramount.

Key Features and Benefits

• 2-Stage Trigger Design: Smooth take-up and crisp break ensure precise, repeatable performance.
• Lightning Bow Profile: Flat-faced, wide-body design enhances trigger control and ergonomics.
• Nanoweapon Coating: DLC finish resists wear and corrosion, ensuring longevity and smooth operation.
• AR-15 / AR-10 Compatibility: Optimized for precision rifles with versatile platform fitment.

The SSA-E’s foundation lies in its unmatched reputation for performance and reliability, making it one of Geissele’s most widely used triggers.

The SSA-E X builds on this success by integrating modern enhancements, particularly for designated marksman rifles (DMR) and precision AR-15 or AR-10 platforms. This trigger’s distinct combination of features caters to those seeking both high performance and long-term durability under varied conditions.

What is Geissele Nanoweapon?

Geissele Nanoweapon (also known as Picatinny DSL) is a family of Durable Solid Lubricant coatings which was developed by ARDEC. It is available exclusively from Geissele Automatics. We continued the development of Picatinny DSL so that its level of corrosion, wear and abrasion resistance is currently unmatched among firearm coatings. Nanoweapon is applied at low temperatures so that the underlying metallurgy of the part is non effected by the application process. Our coating also has a surface hardness roughly equivalent to synthetic diamond. This makes Geissele Nanoweapon harder than sand, easily rejecting carbon and making cleaning a breeze, on top of allowing the firearm to operate normally with less lubrication.

Customer Feedback

These differences would likely not be noticeable to many shooters, but compared to my SSA-E and SD-E it:

- Has far less trigger travel while cocked on safe
- Has a much smoother, more linear first stage in terms of finger pressure and commensurate trigger travel.
- Seems to have a much cleaner break.
- Reset feels much snappier with a much smoother travel back. Travel from fully depressed back to reset seems to be a slightly shorter distance.
- This is subjective, but I far prefer the lightning bow trigger face to the curved or flat face in the previous generation.

The culmination of these features leads to an overall product that an experienced long range shooter may be able to get some more performance out of, and a competition shooter would likely be able to run more quickly and cleaner.

This is a sample size of 3 Geissele triggers, but to me they knocked this one out of the park. I genuinely don't think I would buy another non X gen now after using this one.
