The Geissele SD-3G trigger installs in your lower receiver in the same way that a Mil-Spec trigger is installed. It uses a standard .154” trigger and hammer pin so it will fit in any Mil-Spec stripped lower receiver. It features a flat trigger bow that gives you more leverage to reduce perceived trigger pull weight and improves the tactile feedback so you can feel the reset and pull the trigger faster. Not only does it work in 5.56 or .223 AR-15 rifles, but it works in .308 AR-10 pattern rifles. Each trigger is precision EDM wire cut from heavy duty tool steel with a durable black finish giving you the reliability and durability you can depend on.

Features:
  • Uses Mil-Spec .154” trigger pins for maximum compatibility with lower receivers
  • Works with 5.56/.223 and .308 AR pattern rifles
  • Designed as a 3-gun competition trigger
  • Smooth, consistent hybrid trigger pull
  • Comes with one 4lb. and one 3.25lb. trigger spring
  • EDM wire cut from heavy duty tool steel
  • Features a flat trigger bow that reduces perceived trigger weight and improves tactile feedback
Note: Trigger pull weights are approximate and may vary slightly between rifles.

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.

The best.

Unless you're shooting long distance, this is by far the fastest and most controlled trigger available.

Will this trigger fit on my fm

Will this trigger fit my FM 9mm Tri Lug SBA3?

A little over hyped

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.

Really good trigger

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
