Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.
Ratings & Reviews
Super high value trigger
I own triggers from Larue, Geiselle, Timney, and other manufactures and when these are on sale they can be picked up for around $120. For that price or even regular price they are absolutely fantastic. Maybe I got lucky, but I think my G2S is my favorite trigger in terms of a smooth take up and crisp break.
Can’t go wrong with Geiselle or PA
I like it almost as much as my dads SSA and better than other brands I've used.
<br>PA is also the best site of this kind for fast shipping and great customer service. Order it....especially if it’s during one of PA’s great sales.

bought this trigger for my PSA AR308.. talk about night and day! Anyone who owns one of these knows PSA stock mil spec triggers are complete garbage. Very consistent take up on the first stage with a smooth break. For the money, I don't think this trigger can be beat.

I have the SSA trigger in my CMMG Mutant. I put this in my new S&W M&P 15. I can't tell the difference. I am a Geissele fan! Treat yourself, you won't regret it.
Slick as a Whistle
by Reon K
Not the lightest but it's slick as a whistle, makes shooting fun again. If you're not certain which one to go with try G2S it will not disappoint.
This trigger is awesome. I replaced a milspec that was just about as bad as they come. Totally transformed my rifle into a fine shooter. Primary shipped it fast too.
Best 2 stage for the money
by David -
Just as described, I had a 6.5 trigger pull now its a 4.5 with no creep. The groups will be tighter! and Primary Arms has some of the fastest shipping I have seen!
True American Quality
The first stage feels a bit heavier than an SSA, but the break is outstanding. What surprised me is how fast that this trigger can be run! as per usual, the quality is unmatched and is one more of the most solid yet smooth triggers to be produced. I have used several much more expensive triggers from other brands, and they don't compare to this level of quality.
Great trigger upgrade
by Robert h
Great upgrade for any AR15 and Primary Arms makes this one affordable for everyone.
until I installed it everything and more!!Thought I could live with a milspec trigger until I ordered an i installed G2S trigger better than my hunting bolt actions with timney's very reliable break quit second guessing an order it you won't regret it!! Thank PA FOR THEIR IMPECCABLE SERVICE!!!
Night and day difference from the stock mil-spec trigger in my M&P-15. I see what the hype is about. Pretty easy install. Makes groups tighter very fast and accurate second shot placement. Can't wait til they go on sale again so I can buy another!
I was looking for something that was lighter than my Mil-Spec ALG trigger but just as reliable. Thus my choice for the G2S. It is the same pull and feel as the SSA but without the laser engraving and a different way to hold the hammer pin. Besides that you get the same combat reliability while saving some $.
Money Well Spent!!
If you are looking for a great trigger from a quality company that is below $200 this is the way to go hands down. I was looking to go a little better on my second AR build and decided on this trigger instead of the standard Mill-Spec trigger. OMG!! What a difference! I am going to use this one on future builds for sure. Big shout out to Primary Arms because I was able to try the trigger pull at there location in the demo units first which is what sold me. Their guys are awesome a wealth of knowledge and always willing to help. I would recommend PA to everyone looking for great service prices and product availability.
I thought I was a good shooter until I installed this in my rifle. It made my groupings become cloverleafs. Get one.
If you have a hard time spending $200+ on a trigger this is the way to go. The trigger is two stage and help improve your accuracy especially at longer ranges. The trigger is lighter then military specifications but not so light that you may have a accidental discharge. This would be a great trigger for Law Enforcement or military use. Final note the instalation is easy go on Youtube do a search and the owner of the company will talk you through the steps.
Great Buy For The Bucks
This is my second purchase of the G2S trigger. Both units are exactly as advertised when it comes to performance. Stages break as specified and cleanly. The latest buy was installed in a Ruger SR762 the first in a Wilson Combat lower. The WC has zero creep while the Ruger has a ever so slight almost undetectable creep. The G2S isn't quite up to the performance of my SD-E but for the money it's an excellent choice. Primary Arms' Black Friday sale was great!
Runs about $80 cheaper than some of geisseles' other trigger systems with the exact same specs. Great buy I'll pick one up for my next build
Giessele g2s trigger
Very nice trigger compared to the standard trigger! Very satisfied with it and hard to beat for the sale price!
Geissele G2S Trigger
Exactly as described, always excellent service from Primary Arms.
Good product, good price. Hard to beat Geissele
This was my first purchase from Primary Arms. Excellent shipping, good communication. Very pleased and will buy from again.
Great Trigger, Great Price
This is my second G2S, Smooth and Crisp.Have had no problems and don't expect any.
by Nicholas G
have several Geissele triggers .. top notch my recent purchase is for my wife's rifle ..
excellent upgrade from the factory trigger that came in my ruger sr762
It is a little pricey but is very good quality.
It feels just right. Hard to describe. A bit pricey for just casual target shooting but if you have a reason to get a new trigger and the money, it's definitely worth considering.
