Most Helpful Positive Review Geissele Large Pin Trigger for Colt AR15
Great addition to the average AR that produces a very smooth trigger pull in 2 stages, clear differentiation in those stages and crisp 2nd stage allow for improved target acquisition and smoother follow up shots. I like this trigger and albeit expensive, I believe that is definitely an improvement over the standard trigger and will make a difference with most shooters accuracy when you train with it and get accustomed to the stages.

Large Pin Colt Geissele 05-123

by Bob, Verified Owner from VA, United States Written on March 27, 2025
I was looking for a replacement upgrade trigger for a Colt 9mm AR large pin that had a factory installed sear block. Most drop in triggers were blocked by the sear blocker and I didn’t want to alter the weapon. Installation was easy if you have experience with AR trigger groups. Range test 100 rounds was flawless. Always been happy with Geissele products.

Great Trigger

by PilotDude, Verified Owner from NC, United States Written on February 20, 2024
Absolutely love the Geissele SSA Trigger. I personally like the slightly heavier pull of the SSA over the SSA-E and the large pin fits perfectly into the Colts that require them.

Fantastic trigger

by dbok3, from NC, United States Written on August 12, 2022
Geissele triggers are amazing, that’s why they are used by so many military and police special units. The SSA is a crisp 2 stage trigger that I would recommend to anyone. The initial take up is minimal with a noticeable wall and extremely crisp break on stage 2. I use the Geissele SSA in all my AR’s. One of the best triggers on the market in my opinion.
Pros:
  • Crispness and smoothness of the trigger. Significant reduction in trigger pull.
Cons:
  • Should definitely use an armorer to install.
Best Used for:
  • All around use. Military, police, home defense, hunting, or just target shooting.

Geissele large pin trigger

by Jackson, from CA, United States Written on March 18, 2022
If you need this for your old Colt AR, nothing else will do. Nothing but the best from Geissele…a very nice break from a two stage trigger. Mine came in at an average of 4.5 lbs. Be sure to measure your pin size…it’s impossible to eyeball it accurately. Large pin is .169”…standard pin is .154”…that difference is 15/1000 of an inch. The trigger comes with a slave pin to line up that hole, the hammer pin has to be lined up by eye and is more difficult due to spring tension. Once installed…great trigger!
Pros:
  • General marksmanship
Cons:
  • Precise long range competition
Best Used for:
  • Carried weapons
Would recommend: Yes

The Trigger

by Runewulf, Verified Owner from VA, United States Written on May 20, 2018
Have shot JP, McCormick, RRA, ALG, Hiperfore....for an all around trigger this is the one. You can get a lighter trigger, a faster reset trigger, a more or less expensive trigger... this is the one I keep coming back to for alll around use. Can’t go wrong.
Pros:
  • Price
  • works
Cons:
  • price
Best Used for:
  • everything
