When building or upgrading your AR-15 rifle, one of the most important components is the trigger. There are many triggers out there so you must ask yourself what are you are going to do with the rifle. Are you going to use it for plinking at the range, home defense, competition, or long-range precision shooting? The answer of this question will help you to understand what trigger you will need. The Geissele Super Dynamic 3 Gun (SD-3G) Trigger is designed specifically for 3-gun competition where extremely fast follow-up shots in close quarters are required. It features and extremely short length of pull with a quick reset that puts it between a two-stage and single-stage trigger while still benefiting from the safety and reliability of a combat two-stage trigger. This trigger is non-adjustable, but it comes with two trigger springs so you can choose to have either a 4lb. or 3.25lb. pull weight. The SD-3G is the perfect edition to your race gun that will help you master rapid follow-up shots and target acquisition while under pressure from the timer.
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.

Excellent Trigger
by Christopher -
I've had a couple Geisselle triggers in the past and have been running TriggerTechs for the past couple years. Decided to try this Geisselle since it was on sale. I still like my TriggerTechs but this Super Dynamic 3 Gun trigger is really good. The reset is definitely better on the Geisselle compared to the TriggerTech. Overall, this would be a great trigger for just about any application.
Amazed!

I own Larue MBT2S triggers, Hyperfire triggers, and Shmid 2stage triggers, and have shot several other brands, andI said I would never buy a Geissele trigger because I just figured they were over hyped, but.... I finally decided to buy the sd3g trigger and Wow! This is by far the best feeling trigger I've ever pulled!
Really good trigger
by BillyBryant
I like the trigger but I noticed that you don’t receive everything that’s in the pictures, it comes with the oil and extra spring but no patch as shown. Kinda misleading but I still recommend getting the trigger
A little over hyped
by Whisperpickle
Now don’t shoot the messenger.
I’m coming from cmc, larue and POF triggers so take this for what it’s worth.
I would compare the take up to a single stage trigger with considerable amount of take up then it breaks. I would say it’s almost side by side compared to a cmc 3.5lbs flatty drop in only difference is the cmc had the take up instantly where sd3g has about 1/8” of take up then thr walk.
It’s can be a booger to install the hammer if you have Lethe hands. There’s no grit , and minimal trigger slap on reset. I think that’s where this trigger is so fast at the trigger slap basically trains you to come off the trigger for a desert then engage it again. I used the 3.5lbs speing (I guess they aren’t labeled and there’s no info on thr web on which is which, I just pick the lighted one that was the easiest to bend.
Overall onsale it was a good deal!
I wouldn’t choose it over a cmc if they were the same price.
Will this trigger fit on my fm
by Casey
Will this trigger fit my FM 9mm Tri Lug SBA3?
The best.

Unless you're shooting long distance, this is by far the fastest and most controlled trigger available.
Great Quality Trigger
by Michael
This is an excellent trigger for competition/target shooting as recommended by Geissele. It is definitely NOT suitable for any sort of duty use. It is extremely light and susceptible to bumpfires under certain conditions. While shooting long distance, I inadvertently let a 2-3 round burst go. The heavier trigger is advertised as 4.5 pounds, but there is a statement on the packaging saying it may seem lower on certain rifles. With this trigger being flat, the perceived weight seems to be significantly less the lower you place your finger on the trigger(physics!). I’m not trying to bag on this trigger, as I absolutely love it, but I will have to swap it over to a rifle that is not used for duty.
Great Deal, Don't Hesitate to Buy!!!
by Ken
Best trigger that I have ever owned, hands down. Just as advertised by Geissele himself, it snaps like a carrot. I have read some of the negative reviews for this product and I have not had the same experiences whatsoever. Since installing this on my latest build I have seen noticeable improvements in accuracy, and I will probably put this trigger in every AR that I build moving forward.
Perfection
by James -
I know everything about this trigger has been explained and repeated, but damn, I can't get enough of this thing. I have many different aftermarkets in many different rifles, but I keep coming back to this. My favorite. I already have two but need another. Primary Arms is killin' my wallet with these sale prices.
DO NOT BUY
by jacques -
This trigger has serious hammer follow issues. It will not go bang when you pull the trigger at the "wrong time."
I am not kidding and this is acknowledged by Geissele. When asked for a different model trigger they refused me since I did not buy from them directly.
This trigger is advertised as fast shooting and reliable. It literally jams every ~8 rounds on double taps/rapid fire.
STAY FAR AWAY. I shoot often and with a nice weapon, this is not a unique issue and Geissele is not standing behind their product.
from PA: We have seen nothing but exceptional quality on this trigger and have never seen Geissle turn any one away. Give us a call and we will get this worked out for you.
