Founded on a culture of innovation and robustness, Geissele Automatics has been developing high-precision triggers and components for civilian users, competitors, and specialized forces since 2004. Renowned for the quality of its triggers and its reliability in extreme conditions, the American brand has established itself as a global benchmark.

AR-15 & AR-10 trigger units designed for sport shooting. Direct or stepped trigger, choose your solution.

SD3-G trigger: Extreme responsiveness for dynamic 3-Gun sport shooting.

  • Designed for competition, the Geissele SD-3G offers an ultra-fast hybrid start, between single and two-stroke trigger.
  • With its straight tail and ultra-short stride, it allows for precise and rapid combinations
  • Starting weight : 3.0–4.0 lbs (light spring) / 4.5–5.5 lbs (standard spring)

SSP trigger: Clean and direct break for shooters seeking pure precision.

  • The Geissele SSP is the first truly single-stage trigger designed by Geissele Automatics.
  • With its direct start, without initial run, it offers a clear breaking point and a crisp but short reset, for effective tactile feedback.
  • Starting weight : 3.0 – 3.75 lbs


The Geissele SD-3G is designed for one thing: speed. Engineered for 3-Gun shooting, this hybrid trigger offers a smooth break with instant reset, while retaining the safety of a robust two-stroke-type mechanism.

Hybrid trigger for dynamic shooting

The SD-3G's firing profile falls between a single-stage and a two-stage trigger, with a progressive break and extremely rapid return. This unique behavior offers great smoothness in rapid fire, while remaining predictable.

Flat ergonomics for greater control

Its flat trigger provides a linear feel, reduces the perceived trigger pull weight, and improves tactile feedback with each shot. In use, control is immediate and intuitive.

Performance calibrated for competition

Designed for fast-paced events, the SD-3G offers two configurations:

  • 3.0 to 4.0 lbs with the light spring
  • 4.5 to 5.5 lbs with the standard spring

This is not a trigger for long-range precision shooting, but it excels in fast engagements, IPSC courses or 3-Gun events.

FAQ

Is the SD-3G trigger compatible with all AR15s?

Yes, this trigger is compatible with AR-15 and AR-10 platforms equipped with Mil-Spec pins. No additional milling is required.

Can I use the SD-3G for precision shooting or shooting from a supported position?

This model is not designed for precision shooting. Its very fast trigger pull and short reset are optimized for dynamic competition, not for grouping shots at a fixed target.

Which spring should I choose?

The light spring offers a starting resistance between 3 and 4 lbs for maximum responsiveness. The stiffer spring goes up to 5.5 lbs for those who prefer a little more resistance under the finger.
