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.

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.

smooth!

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

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

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

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

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.
