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.

Exactly what I expected.
Easy installation. Zero trouble installing the SD3G trigger. After installation. I went to the range and fired 60 rds. The trigger was flawless. I am very pleased with the trigger , and plan in installing Geisseles triggers on my other firearms. Money well spent.
Geissele has definately got their act together. I didnt know how I would like the flat trigger but after shooting it, I like it. Really smooth trigger. Primary arms had it on sale and I couldnt pass it up. They shipped quick like always.
awesome as always

Very Nice Trigger
by Dung Tran
I could understand why it cost $245 at first, but now I know why it is. Very well made and feel good.
Mistakes happen, PA resolves them professionally!
I got a good deal on this trigger on black Friday. Received my order quickly buy it was the wrong Geissele (curved, not flat bow). I'm sure they had a lot of orders to fill quickly on Black Friday and the items were similar..It happens.I called PA and they immediately sent out the new trigger and requested I send the old one back when I got new one. 3 day's later I was GTG. I always end up ordering from PA, and this experience confirmed my loyality to them.
Awesome Trigger, buy it
by Joshua Yee
I got this trigger to put in my Spike's Tactical AR Pistol. The installation was easy and took about 10 minutes with minimal effort (even though it was my first trigger install). The 4 lb. trigger breaks like a glass rod and my groupings tightened significantly after the trigger change. Almost no slack to take up and the trigger reset is solid. I've shot a lot of CMC and Timney triggers and this exceeds them by far. It's actually put me in a bad place because now I don't want to shoot my other AR because of the noticeable difference between the grittiness of the stock trigger and the smooth and crisp operation of the Geissele. It's totally worth the extra money, get this trigger!
First time buyer experience
by Marc Klover
I had a really good 1st time buying experience with Primary Arms. Great customer service and friendly staff, unbeatable price on the Geissele SD 3 gun trigger. I highly recommend them and will buy from them again. Super fast shipping.
My second Geissele and it does not disappoint.
by Jason Watson
I have had the chance to demo several triggers and the SD 3-G with its short pull and reset was the perfect choice for this particular AR.
by Scott Reid
I installed this in a Seekins Precision billet lower and love it. Smooth as butter. You won't be disappointed with this trigger.
3 gun trigger
by Russell Foust
I'd been trying to convince myself to spend the money on this trigger for some time and finally did. Couldn't be happier with this trigger. Light feel, super fast reset and consistent. Top it all off and it came with primary Arms famous shipping.....even during the recent craziness in the industry.
by Roland Hesmondhalgh
I'm familiar with Milspec triggers and wanted something better. I knew I wanted a single stage trigger after playing with a POF rifle. Installation is straight forward and made easy with the included starter pin. My only gripe is of the two springs that came with it, one has a tremendous amount of grit to it. Not sure why, but it almost felt like a Milspec trigger even after I lubed/oiled the entire assembly. I put the lighter spring in and now it feels like what you would expect for the money. It does up the cool factor too. I'm annoyed that I can only use this trigger with one of the pull weights but this trigger went into a competition rifle so the lighter trigger isn't a huge safety concern. YMMV
The best AR trigger in the world, bar none
by Steve Stanford
I'm spoiled. I tried all manner of AR trigger before discovering this one. It is literally heads and shoulders above the rest. Nothing compares. Seriously. I can't build a rifle now without one. It's that good. With this trigger I can almost reach full-auto speeds with its light, crisp break, super short takeup, and almost no reset. Forget the drop-in units - they're for pansies. There's a reason why our special forces are using Geissele now.
by james cronk
it really is a nice trigger its super light but its not $260 good
What a trigger
Its true what they say that you get what you pay for.This trigger is all that and a bag of chips
Another piece of Geissele perfection!
I've run about 400 rounds with it through various cqb scenarios in a BCM 14.5" carbine.Couldn't be happier!Very smooth, even, pull with no creep or build.I had read about people having doubles with this trigger. I don't understand how this is even possible.They must be flinching / slapping the trigger or some other terrible habit to get it to double.It is definitely faster and much lighter than a Milspec single stage but I find it had plenty of resistance for me to "feel" it move after I began squeezing. (With the 3.5# spring)I find that the flat trigger bow gives me better feedback as the trigger starts to move.Geissele does not market this trigger for defensive or tactical use. I've been told this is for legal reasons due to the low pull weight. (Not sure if that's true)IMHO, this is the best cqb trigger I've ever had the pleasure of running myself.Shorter, lighter, faster.Bottom line.... Very impressed!Buy it!
Geissele SD-#G is awesome
Light pull, clean break, awesome trigger!
Best trigger on the planet
by Brandon Bowers
Love this trigger. Extremely fast reset. 3.5 pounds pull.You can rapid fire accurately with this.
3 Gun trigger
Nice and sweet, great reset, so nice we now have two of them
Instantly my favorite trigger
The SD3G moved to my #1 spot after the first few dry fires. Smooth, light trigger with super fast reset. I've shot dozens of triggers, including several Geisseles, and this one takes the cake. I have a SD-E on a scoped 6.8 SPC (my choice for a 2-stage precision trigger). The SD3G is just plain fun.
by Mark Meek
THIS IS IN MY OPINION THE BEST 3-GUN TRIGGER ON THE MARKET. PA SERVICE WAS PROMPT.
very light trigger
by brian ruh
This trigger is smooth!
Too much fun!
When I saw this on sale I had to have it. All of the performance of the Tac-Con trigger at around half the price. With a smooth, short pull and an absurdly close reset this allows shooting at near full auto speeds. That being said it does take a little getting used to. If the thing refuses to stop burst firing you can switch out the trigger springs to gain an extra pound of trigger pull weight. Making it into a trigger I can almost recommend for combat/self defense use. I have yet to meet anyone who has regretted getting one of these triggers. ðŸ˜Š
Best trigger money can buy!
Hands down the best trigger for 3 gun or any shooting sport that requires a super fast reset for follow up shots!
