Most Helpful Positive Review Expensive, but works great in Gen 2 Sig Sauer MPX
Sig Sauer was claiming installing an aftermarket trigger without the trigger bridge would void the pistol's warranty. They have now withdrawn that claim saying it won't void warranty, but the aftermarket trigger could be damaged from the high velocity blowback of the bolt carrier. Bill Geissele claimed on a forum that this trigger works with the MPX and their warranty would stand behind using it in an MPX. I installed and tested about 80 rounds through it so far, and it is working very reliably with no issues yet. The original trigger was 9.5lbs pull weight, very gritty, and the worst trigger ...

Geissele SSAE Trigger

by Dullahan, Verified Owner from PA, United States Written on May 2, 2026
This trigger pairs well with the Atrius Forced Reset Selector, G-Lever, and Lever Block. In order for it to function properly. You’ll need a full profile bolt carrier group and H2 buffer. At the moment my setup has no suppressor. It's a full-length AR-15 16” barrel.
Pros:
  • accuracy
Cons:
  • None
Best Used for:
  • Precicion target shooting
Would recommend: Yes

SSA-E Geissele

by GreatWhite Nomad, Verified Owner from FL, United States Written on May 1, 2026
Installation was a breeze, and the trigger pull is exceptionally light with a crisp, clean break. While it is a high-end investment, the performance justifies the premium price because you truly get what you pay for. Highly recommended.
Pros:
  • Smooth
Cons:
  • None

Light and crisp

by CK, Verified Owner from IN, United States Written on December 24, 2025
Replaced the 8# mil spec trigger in my Zion-15. The 2 stage is really nice for prepping the trigger when I'm taking shots past 100 yards.

perfect trigger for my DDM4V7

by freedom, Verified Owner from GA, United States Written on December 12, 2025
Was going back and forth between Geissele trigger and Triggertech and ultimately chose Geissele trigger and not only the trigger but changing the charging handle to Geissele super charging handle as well since I am suppressing it. Feels so much better with these upgrades.
Pros:
  • better trigger than mil spec
Cons:
  • Bit pricey
Best Used for:
  • Upgrade

wow what a trigger

by Av8tor, from VA, United States Written on November 15, 2025
My first trigger I installed myself! Plenty of youtube videos to walk you through the installation, with a little bit of patience it went in really smoothly. The trigger function is amazing. I was so impressed I bought another one. My first install was on a Stag 15, 300 blackout 16"barrel. First stage 2 lbs second stage broke crisp at 1 lb. My second install was on a 300 blackout SBR with the exact same numbers. I cant say enough about the quality and functionality of the Geissele SSA-E trigger. I absolutely HIGHLY recommend this trigger to anyone who takes shooting their AR platform seriously!!!
