The Geissele SD-E (Super Dynamic Enhanced) Trigger is a high-performance, two-stage trigger designed to significantly improve the accuracy and feel of your AR-15 or AR-10. Engineered for precision and target shooting, it's a direct upgrade that installs just like a standard Mil-Spec trigger.
One of its standout features is the flat trigger bow, which gives you more leverage. This not only reduces the perceived pull weight, but it also provides enhanced tactile feedback, so you can clearly feel the reset and take faster, more controlled follow-up shots.
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 target and precision trigger
- Smooth, consistent two-stage trigger pull
- Has a 3.5lb total trigger pull weight
- EDM wire cut from heavy duty tool steel
- Features a flat trigger bow that reduces perceived trigger weight and improves tactile feedback
The SD-E trigger is compatible with both 5.56/.223 and .308 AR-pattern rifles and uses standard .154-inch trigger pins, ensuring it will fit most Mil-Spec lower receivers. Built for durability and reliability, it's precision-crafted using EDM wire cutting from heavy-duty tool steel and finished with a robust black coating. With a total pull weight of approximately 3.5 lbs, it offers a smooth and consistent two-stage pull.

It's Geissele, you already know it's the best
by Aaron -
Very consistent glass smooth break and reset. To me the flat trigger is nice but a slight curve, at the bottom at least, is best for fast accurate use.
It's a Geissele

Enough said. Best 2 stage triggers there are as far as I'm concerned.
GEISSELE SD-E
by chris ursiny
this is a good trigger, i have 2 of them in my 2 vltor a5 lowers, i do recommend using heavy thick syn grease during install so the trigger will be enhanced and function perfect.
The most important upgrade for any AR-15

Just picked up my third Geissele trigger. Waiting for these to go on sale takes patients but if you can wait the deal is worth it. Prior to this SDE I have bought SSA-E triggers. This is the exact same trigger but with a flat trigger instead of the SSA;s curved one. Also my first flat trigger. It feels great, buttery smooth like it should. I thought I would have a hard time adjusting the flat trigger but after a few hundred rounds I got used to it. Which do I like better? They are both great and perform exactly the same, the flat just has a different tactile sensation while pulling the trigger. Tightens groups beyond 100yds and like adding a turbo engine for up close engagements.
Get 'em while on sale! Clean & Crisp Break

As you would expect from Geissele is a quality product. I love the 2-stage trigger because it allows me to fine tune my shot before pulling the second stage. The first stage is very smooth and predictable and the second stage break is very crisp and with minimal reset. The flat bow is a personal preference so YMMV.
Outstanding !

The SDE is an outstanding trigger !
Initially I was a little concerned thinking "would it be too light ?"
It's not - its just right !
I've bought five of these triggers over the past 2-3 years when they are on sale.
Once you try this trigger - its all you will want to use.
Excellent trigger
by Chris
My wife surprised me with this this past christmas and now that i have spent some time with it i thought i'd chime in. I think you are either going to love or hate a flat trigger...so try to test before you buy if at all possible. With that being said, it might be the finest ar trigger i have ever shot. Break is exceptionally clean and reset is very minimal. Is this worth the extra cash over getting an rock river? Absolutely. If you are budget conscious the rra will be great, but this is a totally different level of quality and precision.

This trigger is light! Very easy to install and the flat trigger bow looks great on my v11. A must buy if your looking for a precision trigger. Primary had a great price I couldn't turn down and the shipping was very fast.
Super Dynamic Trigger/Super Dymamic Retailer- P.A.

Amazing trigger, too put it lightly(No pun intended) People tried to talk me out of the flat trigger I'm glad I didn't listen. Also people said it's too light get the SDC-don't listen to them it's awesome. I wanted to order from factory to get the swag kit but they were closed around holidays. Besides that the deal Primary Arms gave me I can buy my own hat and bumper stickers. Also PA was exemplary service even when I was asking for better deal. Of course everyone knows by reading the reviews they are super fast shippers. Thanks PA!
Outstanding upgrade
